The southeastern U.S. state of Georgia votes to choose a senator in a runoff election Tuesday, that will help determine whether the Democratic Party can get strong control of the U.S. Senate.
Incumbent Saxby Chambliss - a Republican - is favored to win, which would thwart the Democrats' ambition to control 60 of the 100 Senate seats.
Sixty seats would create what has been called a "super-majority," giving Democrats the ability to overcome Republican attempts to filibuster, or block legislation from coming to a vote in the upper house of Congress.
Democrats already control 58 seats in the incoming Senate, with a recount in a very tight race in Minnesota yet to be decided.
Chambliss is facing Democrat Jim Martin in today's runoff, after each fell short in November of the majority required to win outright in Georgia.
