Very interesting data from a Monmouth University poll of 8 competitive CDs (CA48, PA01, PA17, NJ03, NJ11, OH12, VA10, WV03). The general take below but there is a ton of detailed data provided in the writeup. Note particularly how well Democrats are doing among white noncollege women, losing them by a mere 6 points, while totally killing it among white college women.
“These eight House districts are particularly competitive because Donald Trump’s vote share was less than Mitt Romney’s in election precincts that encompass just under half of the combined electorate. Republican House candidates are doing worse in precincts where Trump underperformed even after controlling for the partisan lean of those precincts. Furthermore, Republican House candidates are not doing as well overall in Republican precincts as Democratic candidates are doing in Democratic precincts. This performance gap currently offsets the natural GOP lean of these congressional districts.”
