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.
