DeSantis recently won the Republican nomination for governor, helped along by the strong support of President Trump. He will meet Democratic Tallahassee Mayor Andrew Gillum in one of the marquee races this November. Incumbent Gov. Rick Scott (R) is termed out; he is running for Senate against incumbent Sen. Ben Nelson (D).
DeSantis was in his third term representing Florida's 6th congressional district; he and Trump both won here by about 17% in 2016. The district is seen as likely to stay in Republican hands, although it could prove more competitive if there's a strong Democratic wave. The party nominees are Republican Michael Waltz and Democrat Nancy Soderberg.
Sen. Tom Carper is facing a primary challenge from the left by a political novice, Kerri Evelyn Harris. While Carper is likely to win, we have seen Democratic House incumbents ousted by progressive insurgents this year, most recently this past Tuesday in the Massachusetts 7th district. There has been no recent polling of the race. Assuming Carper wins, he will be heavily favored to win a 4th term in November.
Delaware House Primary
The state is one of seven with a single at-large congressional district. Incumbent Democrat Lisa Rochester is expected to win a 2nd term against whichever Republican emerges from Thursday's primary.
Ayanna Pressley, who serves on the Boston City Council, defeated 10-term Rep. Michael Capuano in Tuesday's Massachusetts primary. The district, once represented by John F. Kennedy, is one of the most liberal in the country. As with Capuano in 2016, Pressley will have no Republican opponent in November. Capuano is the fourth House member to be ousted in a party primary this year.
All other U.S. House incumbents that faced primary challenges were victorious, and are expected to win re-election in November. In the 3rd district, where Rep. Niki Tsongas is retiring, a 10-way primary remained undecided. Daniel Koh and Lori Trahan were separated by fewer than 100 votes as of Wednesday AM.
Turning to the U.S. Senate race, Republican Geoff Diehl easily won a three-way primary. He will face incumbent Democratic Sen. Elizabeth Warren in November.
Massachusetts GOP Gov. Charlie Baker won renomination; he will face Democrat Jay Gonzalez.
Both Warren and Baker are expected to easily win reelection.
There's a competitive three-way primary on the GOP side. Regardless of who wins, incumbent Democratic Sen. Elizabeth Warren is expected to easily win a 2nd term in November.
Massachusetts Gubernatorial Primaries
Despite the strong Democratic lean of the state, incumbent Republican Charlie Baker is one of the most popular governors in the country and is expected to easily win a 2nd term this fall.
Massachusetts House Primaries
The state has 9 congressional districts, all held by Democrats. It is the state with the largest number of districts under single party control. All nine seats are expected to stay in Democratic control, so the real question is whether any incumbents lose in the primaries. Keep an eye on the 1st, 7th and 8th districts for possible upsets. There will definitely be a new Democratic member of Congress in the 3rd district; 10 are competing on the ballot to replace retiring Rep. Niki Tsongas.
A New York Times headline sums it up nicely: "A Black Progressive and a Trump Acolyte Win Florida Governor Primaries". Voters in both parties bypassed the establishment candidate. Democrats selected Tallahassee Mayor Andrew Gillum, who upset former Rep. Gwen Graham. Republicans followed the endorsement of President Trump, choosing Rep. Ron DeSantis. The general election here thus takes on echoes of neighboring Georgia, both gubernatorial races "between left-leaning African-Americans banking on the region’s new, diversifying electorate, and ardent, Trump-style nationalists."
As expected, Gov. Rick Scott easily won the GOP nomination for Senate, setting up what will likely become one of the most expensive Senate races in U.S. history.
Rep. Martha McSally defeated hardliners Kelli Ward and Joe Arpaio in a race where Trump made no endorsement. Likely a pragmatic choice by the president, as neither Ward or Arpaio were seen as particularly good general election candidates. McSally will meet her congressional colleague, Rep. Kyrsten Sinema in what will be a closely-contested general election.
Gov. Doug Ducey easily won renomination; he'll face David Garcia in November. Former Rep. Ann Kirkpatrick won the Democratic nomination in Arizona's 2nd congressional district. This is the seat being vacated by McSally, and represents one of the best opportunities for a Democratic gain in November.
Businessman Kevin Stitt won the GOP gubernatorial runoff; he'll meet Democrat Drew Edmondson in November. While Oklahoma is a deep red state, a Democratic flip is not out of the question here in November. Outgoing GOP Gov. Mary Fallin is one of the most unpopular in the country, Edmondson is a strong candidate and polling thus far has him doing better against Stitt than the now-defeated Cornett.
Senate: Sen. John McCain's death has created a vacancy that will be filled by Gov. Doug Ducey. By law, that replacement must be a Republican, although given Ducey's party affiliation that would be expected in any case. It will be interesting to see what direction he goes. The person selected will serve until a special election is held in 2020. The winner of that will complete the final two years of McCain's term.
The state's other Senate seat is up in 2018 and will be a fiercely-contested general election race. Sen. Jeff Flake is retiring. On Tuesday, we'll mostly be watching the Republican primary, where Rep. Martha McSally is hoping to fend off former State Sen. Kelli Ward and former Sheriff Joe Arpaio. Ward previously ran for the U.S. Senate in 2016, where she lost the Republican primary to McCain. McSally has opened up a lead in the most recent polls; a win by Ward or Arpaio would increase the likelihood that this seat flips to the Democrats in November. Rep. Kyrsten Sinema is expected to be the Democratic nominee.
Governor: Gov. Ducey is running for re-election. He is expected to win his primary and will face the winner of a three-way Democratic contest. Ducey will start out the favorite in this race.
House: The state has nine congressional districts. Reps. McSally (AZ-02) and Sinema (AZ-09) are foregoing re-election to run for the U.S. Senate. McSally's seat is a major target for Democrats this fall. Former Rep. Ann Kirkpatrick is favored in a crowded Democratic primary, while Lea Marquez Peterson appears to have an edge for the GOP. Sinema's seat is likely to stay in Democratic hands; former Phoenix Mayor Greg Stanton will be the nominee.
Polls close at 7:00 PM local time (7:00 Eastern except 8:00 PM Eastern for parts of the Panhandle). Where do I vote?
Senate: Gov. Rick Scott faces only nominal competition; he'll meet Sen. Bill Nelson in November. The general election is seen as a toss-up, although Scott has had a small but consistent lead in recent polls. Democrats already have an uphill climb to take control of the Senate, it will be that much harder should they lose the race here.
Governor: The chance to replace termed-out Gov. Rick Scott has created a very crowded primary field in both parties. For the GOP, Rep. Ron DeSantis and Agriculture Commissioner Adam Putnam are the leading candidates. DeSantis' position in the race was significantly strengthened after an endorsement by President Trump in June. On the Democratic side, there seem to be several candidates with a shot at the nomination, including former Rep. Gwen Graham as well as the Mayor of Tallahassee and former Mayor of Miami Beach. The general election is a toss-up.
House: The state has 27 congressional districts. The GOP-held 26th and 27th districts in the very southern part of the state present good pick-up opportunities for Democrats. Both those districts were among 23 (before PA redistricting) that elected a Republican to Congress while voting for Hillary Clinton in 2016. In fact, these two gave Clinton her largest margin of all such districts. The 27th is particularly vulnerable, where 15-term incumbent Ileana Ros-Lehtinen is retiring. One of the candidates running for the GOP nomination to replace her was abducted by aliens.
The state will hold runoffs Tuesday for races where no candidate received a majority of the vote in the June 26th primary. This includes the GOP primary for governor and several congressional districts.
After Tuesday, there are only a few East Coast states that remain on the 2018 primary calendar
Republican Troy Balderson has been certified as the winner of the recent special election in Ohio's 12th congressional district. After absentee and provisional ballots were counted, Balderson defeated Democrat Danny O'Connor by 1,680 votes, or 0.8%.
Once Balderson is sworn in, Republicans will hold 237 seats, Democrats 193, with five vacancies. Those seats will remain unfilled until after the November 6th midterm elections.
Balderson and O'Connor will have a rematch for a full term this November. Most forecasters give a slight edge to Balderson at the moment. Donald Trump won here by about 11% in 2016.

Rep. Duncan Hunter of California was indicted Tuesday and charged with the illegal use of campaign funds over a seven year period. House Speaker Paul Ryan indicated Hunter would be removed from his committee assignments until the matter is resolved.
Hunter is in his fifth term representing a conservative San Diego-area district that supported Donald Trump by 15% in the 2016 election. Only seven of the state's 53 congressional districts voted for the president over Hillary Clinton that year.
Hunter was renominated in California's top-two primary in June. Even if he were to decide not to run, there is no good mechanism to remove his name from the November ballot. Additionally, California does not allow for write-in candidates.
The indictment has opened up yet another opportunity for a Democratic flip as the party attempts to gain control of the House in November. As of Wednesday morning, both Sabato's Crystal Ball and The Cook Political Report have moved this race from safe Republican to leans Republican. Nathan Gonzales of Inside Elections has not yet made a change, although he seems to have his priorities in order:
