Geithner plays attack dog

Chandler, Arizona (CNN) - He’s President Obama’s top economic advisor. But these days, Treasury Secretary Tim Geithner is delving into raw politics.

CNN caught up with Geithner at an Intel Corp. manufacturing plant in Chandler, Arizona Tuesday. Geithner’s location alone is significant: Arizona is key to the president’s reelection efforts – a swing state with 10 electoral votes where Obama garnered a respectable 45 percent of the vote in 2008 despite the fact that Arizona’s own John McCain was on the opposing ticket.
