Ten days after America went to the polls, three Senate races in Alaska, Minnesota and Georgia have yet to be decided.

In Georgia, incumbent Sen. Saxby Chambliss (Rep.) finished ahead of Jim Martin (Dem.) by about 110,000 votes but with only 49.8 percent of the popular vote.

According to Georgia law, a candidate must win 50 percent of votes to be declared the winner. The runoff election on Dec. 2 will not include Libertarian candidate Allen Buckley, who won just under 4 percent of votes on Nov. 4.

The high-profile runoff is attracting a number of visitors to the state of Georgia. Sen. John McCain (R-Ariz.) appeared at a rally with Chambliss in Atlanta on Thursday, and former Arkansas governor Mike Huckabee will appear with the campaign this weekend. “Our number one priority is turnout,” said Michelle Grasso, communication director for the Chambliss campaign. “We have field offices all over the state making sure supporters know they can vote as early as Monday.”

More than 100 aides involved from President-elect Barack Obama’s campaign are in Georgia to help the Martin campaign maximize turnout.

Kate Hansen, the Martin campaign press secretary, said their main focus is “getting our grassroots outreach in place” and making sure turnout is high. The key to victory, she said, “is continuing to show Georgia voters that Jim Martin is someone who will stand up for them.”

Voter turnout for the run-off election is expected to decrease significantly with only two candidates on the ballot. With 57 representatives in the Senate, Democrats look to the three races to determine whether the party begins the next Congressional session with 60 seats and a filibuster-proof majority.

Michael Crespin, professor of political science and an expert in congressional elections, said the race in Georgia will likely be the key factor in deciding whether Democrats have a majority of 59 or 60. But he said 60 Senate seats “doesn’t guarantee anything.”

It would “allow Democrats to enact more of their agenda,” he said, “as long as they vote cohesively and as long as Obama remains popular.”
