Sabato's Crystal Ball has updated a few race ratings for the November elections. They also discuss a few other contests where changes were considered, along with a recap of this past Tuesday's key primary results.
The maps below reflect their current ratings for Senate, House and governor. Click or tap any of them for an interactive version.
Republicans currently have a 51-49 edge; Democrats need a net gain of two to take control. That is an uphill climb in a year where the party is defending 26 of the 35 seats up for election, including 10 won by Donald Trump in 2016.
Of the 54 seats seen as most competitive (rated toss-up or leaning), Republicans hold 49 of them. This includes the vacant OH-12, which will be filled by a special election in August. 218 seats are needed for control.
There are 36 gubernatorial elections in 2018.
