President Barack Obama's reelection campaign is pulling down its attacks ads against Mitt Romney in the aftermath of the tragic mass shooting at a movie theater in Aurora, Colorado, a spokeswoman says. "We have asked affiliates to pull down our contrast advertising for the time being," Jen Psaki told reporters, according to a pool report from the Washington Post's David Nakamura, traveling with Obama on a campaign swing through Florida. "It takes time for stations to be able to do this, but we are making every effort."
