The Republican National Committee is ramping up its spending on campaign ads, spending $5 million in one day on anti-Obama ads, writes the New York Times.

“In a single day, the committee paid for a $5 million advertising purchase by OnMessage, a media firm in Alexandria, Va., that represents Republican candidates. It was the fourth independent expenditure — a campaign finance technicality that allows the party to name Barack Obama in the advertisements — made by the committee in the presidential race.

“The money is paying for two television advertisements, including one, “The Chicago Way,” that came out last week. It talks about “shady politics” and names what it depicts as a rogue’s gallery of Obama acquaintances, including Antoin Rezko, the disgraced developer; William M. Daley, the brother of the Chicago mayor; and William Ayers, the university professor who was a member of the Weather Underground in the 1960s.”
