A day after the McCain campaign released a Web ad that highlights Obama's association with William Ayers, the Republican National Committee is piling on with their own TV ad that goes one step further.
Tomorrow, the RNC's independent expenditure unit announced that it will begin airing an ad hitting Obama on Ayers, Tony Rezko, and Chicago politics, reports NBC's Mark Murray.
"But the ad will run only in the battleground states of Indiana and Wisconsin, which border Illinois."
