While Republican voters continue to fluctuate on their choice for the 2012 presidential nominee, Megadeth frontman Dave Mustaine has made a firm decision as to who he wants to see in the White House: former Pennsylvania Senator Rick Santorum.

"Earlier in the election, I was completely oblivious as to who Rick Santorum was, but when the dude went home to be with his daughter when she was sick, that was very commendable," the thrash metal star told MusicRadar.com.

"You know, I think Santorum has some presidential qualities, and I'm hoping that if it does come down to it, we'll see a Republican in the White House... and that it's Rick Santorum."

Mustaine said he was supporting Santorum over the primary's delegate leader Mitt Romney because he was distrustful of the means by which the former Massachusetts governor created his immense wealth.

"I've got to tell you, I was floored the other day to see that Mitt Romney's five boys have a $100 million trust fund," Mustaine told the music website. "Where does a guy make that much money? So there's some questions there."

The platinum-selling recording artist said that he briefly supported the candidacy of former House Speaker Newt Gingrich, but ultimately decided he did not have the gravitas to be the president of the world's most powerful country.

"And watching Newt Gingrich, I was pretty excited for a while, but now he's just gone back to being that person that everybody said he was -- that angry little man," the 50-year-old said. "I still like him, but I don't think I'd vote for him."

As for Ron Paul, Mustaine said he simply could not support some of the Texas congressman's most extreme views.

Megadeth's lead vocalist said Paul will "make total sense for a while, and then he'll say something so way out that it negates everything else."

The rocker said that while he is now supporting Santorum, what he hopes for most in January 2013 is that Barack Obama will not be inaugurated for a second term.

"I can't bear to watch what's happened to our great country," Mustaine said. "Everybody's got their head in the sand. Everybody in the industry is like, 'Oh, Obama's doing such a great job...' I don't think so. Not from what I see."
