This is the right take (if I’m reading it correctly), but let’s talk about that article claiming the Democratic wave is receding (nymag.com/daily/intellig…). Oh boy... Best evidence of REAL change in the wave is in actual voter behavior. If Democrats stop posting gains in special elections over time, they should worry more. Of course, they haven’t (yet?). These claims are almost all based on declining D margin in the generic ballot, which...

27% in now. Unclear if Lamb can pull this off. He’s running out of votes in Allegheny Not sure if anyone else is seeing this or my data is messed up, but pretty interesting nugget — seems like Clinton precincts are voting a little worse for Lamb than her, but turning out much more. R precincts going more for Saccone than Trump, but voting far less.

thecrosstab.com/2018/03/13/pa-… Before 8PM rolls around, I want to cover what the data say to expect in this contest. This thread will start off running through my predictions, will cover how I’m projecting the race, and will turn into a live blog with graphics when the votes start to come in.

#New PA cong. map increases D chance of winning the House majority by 4%. They only need a 6.8% generic ballot margin now (down from 7.7) to be favored.

Diff. will be closer to 10% in Nov when uncertainty from polls is ⬇️. Redraw is a very big deal.

One major reason the new PA map is such a big gain for Democrats is that it solidifies, not just tips, PA districts in Philly burbs. Also creates one additional vulnerable R district. (Easily seen in this map made by @JMilesColeman)

New #PA Congressional map is pretty much the best one Democrats could have hoped for. At least 2 pickups in neutral environment, likely ability to win 11 in current D+6 environment. Post coming PA redraw creates map that is almost entirely drawn from scratch. Huge shifts from 2016 plan all over the place. Dems favored to win 9 seats there in almost any national environment.
