At least we know now he wasn't lying or even flip-flopping when he said he didn't understand economics. Oh well, Phil Gramm has rejoined the campaign; it can be his job to remind him. A couple of times a week:

Sen. John McCain (R-Ariz.) said in an interview Wednesday that he was uncertain how many houses he and his wife, Cindy, own.

"I think — I'll have my staff get to you," McCain told Politico in Las Cruces, N.M. "It's condominiums where — I'll have them get to you."

Can't remember how many houses he owns, can't tell a Sunni from a Shia, thinks Pakistan shares a border with Iraq, has both supported and opposed offshore drilling, the Bush tax cuts ...

... and Obama is losing ground to this guy?
