UPDATE: Romney says Rubio is being fully vetted.
Jonathan Karl of ABC News is reporting that “Republican sources” are telling him that Mitt Romney is not even vetting Sen. Marco Rubio (R-Fla.), revealing that Rubio has not been asked to provide background information or told to complete financial disclosure forms.
If this is true, then Rubio is out. It’s not conceivable that someone as organized and methodical as Romney would not have started vetting Rubio already.
Though he would generate reams of excitement among conservatives, Rubio probably would present problems for Romney personally. Mitt is not the most exciting candidate, and the Romney campaign is probably concerned about the warm up act upstaging the star of the show.
But at a more basic level, Rubio is a Tea Party conservative, and Romney is not. His presence on the ticket might interfere with Romney’s message, and probably just makes Mitt uncomfortable.
Not saying Rubio isn’t the best choice. Just saying Romney may not want to deal with someone over on his right, both during the campaign and his presidency.
