To get a sense for how vulnerable the Republican House members are, I looked at every Republican-held seat in the country that has a Partisan Voting Index (PVI) of R+10 or less. The seat the Republicans lost in Mississippi last night has a PVI of R+10. I also added in a few seats that are more Republican than R+10 but which have very well funded Democrats in the race.

As you’ll see there are over seventy-five potentially competitive seats, and another thirty or so that could be competitive if the Dems find a candidate, or if the candidate improves their fundraising, or if the DCCC can devote enough money to make up for a financial disadvantage.

Simply put, the Republicans should be absolutely terrified. More than a third of their seats are in jeopardy.

You can look up the the cash-on-hand for every candidate here. I used the following format for each seat:

Congressional District (CD), Partisan Voting Index (PVI), Incumbent/Open Seat, Challenger, Challenger’s Cash on Hand (COH). Enjoy.
