I saw a suggestion that said Romney needs to take a big screen TV with him to every event with the debt clock running in the background. When he's done speaking, point to the amount our national debt has gone up just in the amount of time he was speaking.
On a side note, I didn't support Romney from the start and he's definitely not my choice as our candidate but I'm all in now. I think a lot of republicans feel the way I do and that is exactly what Obama and the lefties didn't want to happen.
