As followers of this year's presidential campaign await news of vice-presidential choices, other questions have taken hold. They center around housing — how many homes John McCain owns, for instance, and how Barack Obama came to own one in particular.
McCain's answer to a question from Politico.com's Mike Allen about how many houses the senator and his wife owned drew a noncommittal response.
"I'll have my staff get to you," was his response. It wasn't long before Obama seized on the issue.
"By the way, the answer is John McCain has seven homes," Obama said. He said the episode illustrates a "fundamental gap" between McCain and everyday Americans.
Both campaigns are now running national TV ads on the subject. McCain's response ad questions Obama's relationship with tainted developer Tony Rezko, who the McCain camp says helped the Illinois senator acquire an expensive house.
