WASHINGTON – Democratic presidential hopeful Barack Obama may be in the lead in the polls, but he’s leaving little to chance especially among younger voters.

He went on MTV to answer questions from young voters ranging from student loans and taxes to gay marriage and whether ordinances should be passed prohibiting sagging pants — yes sagging pants.

“I think people passing a law against people wearing sagging pants is a waste of time. We should be focused on creating jobs, improving our schools, health care, dealing with the war in Iraq,” Obama said.

But he added: “Having said that, brothers should pull up their pants. You are walking by your mother, your grandmother, your underwear is showing. What’s wrong with that? Come on.”

MTV said his Republican rival John McCain was offered a similar opportunity to answer questions from young voters, but he declined.
