^ you will especially see that effect in the Senate races. In this toxic political atmosphere, you are not going to level with some WaPo pollster.
I don't know, yes, a R gain in the Senate, doubt it will go anywhere near a super majority of 60, probably about 54, 56. Trump's approval numbers among all adults is just irrelevant next week, you want to look at likely votes in swing districts instead.
The old saw is late undecideds go with the incumbent, but many of these GOP House seats are open, there is no incumbent on the ballot, since so many GOP members retired. Many of them were neverTrumpers. Need to go through them all this weekend, much harder for me to predict than who would win the World Series this year. Everyone, including me, picked the Red Sox and they did.
