That would be McCain's home (well, one of them ten homes, anyway).
Remember when McCain said that Rick Davies, his campaign manager and lobbyist-in-chief, "has had nothing to do with [Freddie Mac] since , and I'll be glad to have his record examined by anybody who wants to look at it"? Well, as it turns out, he should not have challenged anybody to examine Davies's record, because the NY Times and Newsweek did, and here is a summary of what they found.
This is particularly important because the McCain campaign has been running a smear ad campaign against Obama for his very tenuous ties with former (and discredited) Fannie Mae chairman, Frank Raines. The Obama campaign has denied Raines's role as an Obama economic adviser, and Time's magazine Karen Tumulty has already called the ad in question an attempt by the McCain campaign to play the race card on Obama.
Turns out that McCain's campaign ties to Freddie Mac are at least as egregious as Obama's ties to Fannie Mae, arguably more.
Which reminds me: those who live in glass houses should not throw stones. Particularly when they have so many lobbyists on their campaign and so many houses to fill with them that they have trouble keeping score.
