ATLANTA (AP) -- Voting is under way in today's Senate runoff election in Georgia.
It's one of the two unresolved races Democrats need to get a filibuster-proof 60-vote majority in the Senate.
It came about because both Republican Senator Saxby Chambliss and Democrat challenger Jim Martin failed to get 50 percent of the vote in last month's three-way contest. This time, the Libertarian candidate is off the ballot.
The runoff has drawn some national political heavyweights to Georgia, including Senator John McCain and other former GOP presidential candidates who've been stumping for Chambliss.
Martin has been echoing President-elect Barack Obama's message of change, though the most Obama has done for him is record a radio ad.
The other undecided Senate race is in Minnesota, where a recount continues.
