Both Louisiana and Georgia require a winner to get a majority (50 percent plus one vote). Right now that looks unlikely in both states.
In Georgia, where Republican David Perdue and Democrat Michelle Nunn are competing for an open seat, the RealClearPolitics average of public polls rates this race as a tie – with both averaging 45.4 percent of the vote. A libertarian candidate, Amanda Swafford, has 3.8 percent of the vote.
This seat is being vacated by a Republican, but Mr. Perdue, a businessman, has gotten in hot water for comments about outsourcing jobs. If neither of the front-runners crosses the 50 percent threshold, it’s on to a Jan. 6 runoff.
Same story, different circumstances in Louisiana. That state doesn’t have a primary. All candidates run on Nov. 4, and if no one gets a majority, the two top winners head to a runoff on Dec. 6. Right now, incumbent Democrat Mary Landrieu is running ahead of Republican Bill Cassidy in a jumble of candidates. But a runoff looks certain. Senator Landrieu is far from 50 percent, and in this red state, where neither she nor the president is popular, a match between the two highly favors Mr. Cassidy.
