Today's runoff race for one of Georgia's US Senate seats is crucial for Democrats in their attempt to get a 60-vote, filibuster-proof majority.
The Atlanta Journal-Constitution drills down the significance of today's vote:
Palin and U.S. Sen. John McCain (R-Ariz.) lost the Nov. 4 election to Obama and running mate Joe Biden. The McCain-Palin ticket, however, carried Georgia by about 200,000 votes, and Chambliss brought Palin to the state in a last-minute effort to push conservative voters to the polls for today's runoff.
Democrats want to oust Chambliss and elect Martin to help secure a 60-vote, filibuster-proof "super majority" in the Senate.
Democrats now have 58 seats in the upper chamber, with only races in Georgia and Minnesota to be resolved.
Republicans have vowed to hold Chambliss' seat at all costs.
