Last weekend in DC, there was a sort of..."Last Call" party for Barack Obama.

It was a massive phone banking telethon - designed by Obama's national headquarters, organized and put into action by the DC for Obama office.

Rachel, a full-time volunteer, was on hand to talk. She had two cell phones, numbers scratched in Sharpie on the back of each and a dazed but focused look.

"Our job in the DC Office is to mobilize DC Residents to turn out Virginia Voters."

Neighborly...or nosy? Check out this video to see how the massive mobilization effort functions - and what it is like to witness the Obama grassroots grow.
