Today will likely reveal the outcome of Georgia’s marathon U.S. Senate race. Voters return to the polls for a special runoff election.

Georgia is the only state requiring a runoff if the leading candidate in a general election fails to exceed 50 percent of the vote.

In last month’s general election, Republican Saxby Chambliss, the incumbent, fell just short of that, receiving 49.8 percent of the vote in a three-way race. Democratic challenger Jim Martin scored 46.8 percent with Libertarian Allen Buckley trailing at 3.4 percent.

Conventional wisdom (and recent polls) would suggest Chambliss has the advantage in this “red” state. However, Martin has inherited a high-tech and well-organized “get out the vote” system from the Obama campaign, which has been actively using its vast email database to rally likely supporters.

When I arrived at my own precinct this morning, the flow of voters was steady, but light. Compared to the massive turnout in the general election, it’s expected that relatively few voters will determine the outcome of the runoff.
