There are so many problems with this list, but since I'm drunk atm and don't like to make long drunk posts for obvious reasons, I'll just say that Artur Davis and Joe Baca are Republicans.
It is true that both changed to the Republican party recently, but they have both once again changed their party affiliations. Joe Baca is now an independent, and Artur Davis is once again a Democrat.
While I agree that neither would be strong candidates for office in their respective states, neither of them are registered Republicans today.
