Another interesting question: Who becomes GOP leader if Dems win the House?
Isn't Scalise very, very likely? McCarthy seems not to have the necessary support within the caucus. Cathy McMorris Rodgers is a possible dark-horse, as perhaps are Patrick McHenry/Greg Walden.
I can see McCarthy soon resigning from leadership altogether. Scalise is a possibility, though I don't think the more moderate Republicans would support him. McMorris Rodgers is a better pick, she can appeal to both the Main Street Partnership and Study Committee. McHenry and Walden are also good choices, the latter will be termed out of his post as NRCC Chairman, he may want to jump to another spot.
