One surely hopes that this is the police check-in line and not a line for donuts....... (just joking around, officers).
This was the first campaign rally I've ever attended, and this is the first political campaign I've volunteered to assist. I strongly support President Obama in his re-election campaign. If you're interested in volunteering - just go online and sign-up to help. It's easy to do, and you meet a lot of interesting people.
