First, the person who’s likely not being vetted – ever: Rick Santorum. When he was asked on CNN about serving in a Romney administration, he said: ”Yeah, it is pretty much a flat no.“

However according to Taegan Goddard: Despite reports to the contrary today, Mitt Romney told the media that Sen. Marco Rubio (R-FL) is being “thoroughly vetted as part of our process” to select a vice presidential running mate.

Meanwhile, Think Progress found something interesting in Marco Rubio’s new memoir:

In the new memoir An American Son, Sen. Marco Rubio (R-FL) — the son of Cuban immigrants — reveals that he would be willing to cross the border into the United States illegally to provide a better life for him and his family: “Many people who come here illegally are doing exactly what we would do if we lived in a country where we couldn’t feed our families,” Rubio writes in his book, which went on sale Tuesday. “If my kids went to sleep hungry every night and my country didn’t give me an opportunity to feed them, there isn’t a law, no matter how restrictive, that would prevent me from coming here.”

Many, many people feel that way of course. But you have to wonder how that little admission will play in Tea Party USA — or how (if?) it will be covered on Fox “News.”
