Romney, Obama Volunteers Campaign Through Sandy

President Obama and Mitt Romney may be canceling campaign events, but their volunteers in swing states are still going door-to-door and making phone calls during the final week before Election Day.

Candidates cancelled or changed 30 events due to the superstorm Sandy. Romney's rally in Ohio was cancelled today and rebranded as a service event.

"The campaign could be over as we know it," Joe Scarborough said on MSNBC after Obama spoke about the state of the storm Monday.

But the North Carolina branch of the Obama campaign must not have heard him. They tweeted photos of members of the Winston-Salem State University marching band waving American flags and carrying Obama signs under umbrellas that afternoon.

Ann Romney canceled a visit to New Hampshire today, but that didn't deter supporters. New Hampshire's Romney spokesman Tommy Schulz said some of those who planned to go to the events showed up to volunteer instead.

"We have our people in our offices still phone banking," Schulz said shortly after 11 a.m. on Monday. And if phone lines go down, volunteers plan to use cell phones. Schulz said the campaign has a mobile office, a driver who travels around the state with cell phones to help volunteers call voters on behalf of the Republican candidate.

New Hampshire Romney volunteers are also "still knocking on doors until it's unsafe to do so," Schulz said Monday.

Virginia's 13 electoral votes make it an important state to win this election, but volunteers there are organizing to help with relief efforts in their candidates' names.

The Obama campaign has shut down several offices in Virginia, and staff is urging everyone to follow safety guidelines. Where it's safe, others are still hard at work.

"Through emails, on Facebook, Twitter and BarackObama.com, supporters are being invited to donate to the Red Cross to support the relief effort," Obama for America Virginia Press Secretary Marianne von Nordeck said in an email Monday. "In areas where it is safe to do so, our grassroots organization is moving ahead with our efforts to reach out to voters and get our supporters to the polls on Election Day."

Romney campaigners in Virginia, like their New Hampshire counterparts, are organizing donations of supplies like clothes and food.

Romney for President Virginia Communications Director Curt Cashour tweeted photos Monday afternoon of donated relief supplies, both at Arlington campaign headquarters and in the back of a Romney campaign bus.
