Megadeth frontman Dave Mustaine's not ready to cast his vote just yet.

"Contrary to how some people have interpreted my words, I have not endorsed any presidential candidate," the rocker said in a release after earlier reports had him backing Republican Rick Santorum on Wednesday. "What I did say was that I hope to see a Republican in the White House.  I've seen good qualities in all the candidates but by no means have made my choice yet.  I respect the fact that Santorum took time off from his campaign to be with his sick daughter, but I never used the word 'endorse.'"

In an earlier interview with MusicRadar.com, Mustaine had critical remarks for the rest of the Republican field.

"I was floored the other day to see that Mitt Romney's five boys have a $100 million trust fund. Where does a guy make that much money? So there's some questions there," he said. "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. I still like him, but I don't think I'd vote for him."

He added that Santorum, who won caucuses in Colorado and Minnesota as well as the Missouri primary last week, "has some presidential qualities."

"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 was quoted as saying.

Mustaine is the latest rocker to come out in favor of a Republican candidate, with Kelly Clarkson drawing fire in recent weeks for her Twitter backing of Ron Paul.
