Megadeth lead singer and guitarist Dave Mustaine spoke with the CBC's George Stroumboulopoulos about politics, which he says is an essential concern.

"You have to be to live in America, because things change every day there. You just keep getting more of your rights taken away."

Freedom of speech is Mustaine's key rights concern: "Because I've got a big mouth."

As for his political affiliation, "I kinda vote for the lesser of two evils," he says, which would appear to be Republican.

"Rick Santorum … he just looked like he could be a really cool president, kind of like a JFK kind of guy."

As for U.S. President Barack Obama, "I know he was born somewhere else than America."

Pressed on the matter, Mustaine says, "I want to change the subject. I don't want to talk about my president."
