WASHINGTON (AP) — A suspenseful election night is one thing. But what if it stretches out for a month or more?

A few tight races in states with quirky election laws make it possible that voters on Election Day won't decide which party controls the Senate.

Louisiana's election laws are a chief reason. Strategists expect a Dec. 6 runoff.

They say Democratic Sen. Mary Landrieu and top Republican challenger Bill Cassidy will struggle to exceed 50 percent on the crowded, all-candidates Nov. 4 ballot.

Control of the Senate could hang on a Louisiana runoff.

Republicans need six more seats to rule the chamber. Several possible scenarios get them to five pickups without Louisiana.

The possibility of a Georgia runoff and a late vote count in Alaska could further complicate the outcome.
