In other campaign news, Senator Obama has begun airing a new television ad criticizing John McCain for failing to remember how many homes he and his wife own. During an interview with the website Politico, McCain was asked about his multiple homes.

Sen. McCain: “I think — I’ll have my staff get to you. It’s condominiums where — I’ll have them get to you.”

McCain’s staff says the Arizona senator and his wife own four homes: two in Arizona, one in California and one in Virginia. But it is reported the McCains actually own at least seven properties worth around $14 million. McCain’s comments come just days after he said the threshold for considering someone rich is $5 million.
