At the risk of going slightly against the "Trump sunk the GOP" narrative, I think it's reasonable to say this probably adds a significant bump to the GOP slate, with more of a focus on economics and less on abortion and the near daily headlines that turned educated women voters hard against the GOP.
My gut guess is that this probably bumps Walker and Laxalt over the line; maybe Lake as well?
Given how weak Mastriano was down ticket Oz probably is sunk still but maybe only by 1-3%. Obviously a few more Republicans squeak by in the House, maybe up to 230 or so?
By Walker you mean getting him to lead the first round or outright getting him above 50%.
