This evening, the Romney campaign will unveil a new video during the RNC called "Switchers," a 2:30 spot featuring former Obama voters who have decided he's not their guy in 2012. Watch:

Romney needs to remind people that they aren't happy with the current administration, and he can best accomplish it with videos like this: ordinary people talking about the optimism they felt for Obama, and the subsequent struggles they faced when he didn't follow through on promises of "change."
