Lot of Republican-held marginal seats that were shored up this year.
I suspect the Dems will need to win the popular vote in the House by about a 53%-47% margin for the odds to go their way that they will take control over the House. The tipping point is about a 2.75% GOP PVI CD, and in addition to that, you now have the Pub incumbency factor, which is typically worth about 3 more points if the incumbent is reasonably competent. It is going to be a
very uphill climb for the Dems. The Pubs have been rather systematically building a firewall of some formidability in a coordinated national effort. It was a top priority of the RNC, and they had a whole team put together to coordinate with the Pub state legislatures.
