McCain Jumps Ahead of Obama in Latest Poll

John McCain bested Barack Obama 50-46 percent among registered voters in the latest USA Today/Gallup poll, jumping 11 points over his previous showing and taking his biggest lead since January. This new lead in the polls has to be credited to a well-received Republican Convention last week fueled largely by the surprise pick of McCain's vice presidential running mate, Sarah Palin. The numbers out Monday show McCain wiped out a 7-point lead Obama received after the Democratic Convention two weeks ago.
