McCain: Palin was 'better candidate' than Romney

Mitt Romney's tax returns had nothing to do with Sen. John McCain's decision to choose Sarah Palin as his running mate in 2008, according to the Arizona Republican, saying he chose the former Alaska governor because she was a "better candidate."

McCain received more than two decades worth of Romney's tax returns as the former Massachusetts governor was undergoing the vetting process four years ago, far more than Romney has released publicly in the 2012 campaign. Democrats have questioned whether McCain saw something untoward in those tax returns and decided to choose Palin instead.

But on Tuesday, McCain flatly rejected that assertion and grew angry at questions over his decision to choose Palin over Romney.

"Of course not," McCain told POLITICO when asked if the contents of Romney's tax returns disqualified him from the selection process. "I don’t know what depths these people won’t reach. Obviously, it’s just outrageous. That’s just outrageous. It shows the – it’s so disgraceful for them to allege something that they have absolutely no knowledge of."

Asked why he chose not to go with Romney, McCain said: "Oh come on, because we thought that Sarah Palin was the better candidate. Why did we not take [Tim] Pawlenty, why did we not take any of the other 10 other people. Why didn’t I? Because we had a better candidate, the same way with all the others. ... Come on, why? That’s a stupid question."

Steve Schmidt, McCain's top campaign adviser in 2008, told the Huffington Post that the contents of the tax returns were not viewed as a problem for their campaign. But Romney's vast wealth was seen as a political liability that McCain could ill afford, he said.

"Sen. McCain got caught flat-footed answering a question about how many houses he owned," Schmidt told the news website. "In fact, they were Cindy McCain's properties but that distinction was lost in the political optics and we knew it would be a big liability that the presidential and the vice presidential candidates together owned more than a dozen homes. It was like something out of a 'Saturday Night Live' skit. I mean, come on."
