Under attack because McCain couldn't remember how many homes he has, his campaign produced their own attack advertisement. Factcheck.org couldn't find any truth in it.
* The ad says Chicago power broker Tony Rezko got "political favors" including "$14 million from taxpayers." But there's no evidence of any connection to the Obama home purchase. The $14 million was to build apartments for low-income seniors. Obama wrote a letter supporting the "worthy" project, but both men say Rezko didn't ask for the letter.
* It says Rezko "purchased part of the property [Obama] couldn't afford." Rezko's wife did buy an adjoining tract but later sold the land at a profit. Obama paid market price for his home.
