President Barack Obama says the rise of new political action committees guarantees that there will be a lot of negative ads before November's presidential election.
Obama says he would prefer to get the "big money" that funds the so-called super PACs out of politics. He says court decisions authorizing the funding of super PACs means it's hard for a candidate to get his or her message across without using those resources.
Obama wouldn't say whether his campaign or outside groups supporting him would avoid negative ads.
He says a candidate can't win by simply attacking opponents and going negative. He says candidates must also explain their vision for the country.
Obama spoke during an interview on NBC's "Today" show.
