Is McCain's memory really that poor, and if so, what does it say about his ability to be president? Or is the number of houses he has such an unimportant question to him that it's not worth remembering? That he has a house everywhere he goes, so why bother singling them out to remember?
My question is, what does it say about the politics in this country when the current president's party is about to nominate someone who doesn't even know how many houses he owns?
