John McCain's economic team has two people on it who have lobbied for Fannie Mae and Freddie Mac...

'Rick Davis: Before becoming McCain's campaign manager, Davis "served as president of an advocacy group led by Fannie Mae and Freddie Mac that defended the two companies against increased regulation." As noted in the Progress Report, "During his tenure, Davis moved to challenge even the smallest measures to make sure that Fannie Mae and Freddie Mac are be held more accountable for their actions."'

'William Timmons: A consummate Washington insider, Timmons, who McCain tapped to head his presidential transition team, was a lobbyist with Timmons and Co., and lobbied for, among others, Freddie Mac. According to Time, "He has registered to work on bills that deal with the regulations of troubled mortgage lenders Freddie Mac and Fannie Mae."'

That last one appears also to be the one who lobbied on behalf of Saddam.
