President Obama’s approval rating climbed to 52 percent, his highest rating in many months, according to Gallup’s latest poll. The last three days of the Democratic National Convention gave him a 7 percent bump in approval over three days, with a 3 percent hike in just the past 24 hours. Mitt Romney received no bump in the polls from the RNC, dropping from 47 percent before the convention to 46 percent. The DNC also surpassed the RNC in ratings; even competing with the opening night of NFL football, more people tuned in to Bill Clinton’s DNC speech than the second half of the Cowboys-Giants game.
