Headcount, an organization that registers voters at rock concerts, says adding Romney to the ticket was a smart move. Why? He's charismatic and he helps with swing voters. Also, Ryan will help push turnout.
Most polls have President Barack Obama up by a point or two, with only about 7 percent of voters undecided. That means it’s unlikely there will be any huge swings between now and November, and the race will largely come down to who turns out on Election Day. Ryan is deeply popular among the Republican party base and has conservative bona fides that some say Romney lacks. His presence on the ticket can only serve to mobilize the Republican electorate and that could make a difference on Election Day.
