According to CBS/YouGov’s data (but not their interpretation), if the partisan turnout is the SAME as 2016, Republicans will get more votes than Democrats in the House races. And registration and early voting suggests they’ll do better.
(With THEIR turnout model, Dems win by 7%.)
I don't know about the CBS data. But just the data on this thread says if Trump wins again, there are so many Democrats in Trump districts Nancy P. should lose the House. Now, candidates matter, incumbency counts, as does fundraising. But the House/Senate districts in the swing states are going to benefit from the Trump/RNC GOTV efforts.
How do they get Dems winning by 7% with increased GOP turnout from 2016! With the Trump wave we are going to retake many of the seats lost in Trump districts.
