WASHINGTON — A suspenseful election night is one thing, but what if it stretches for a month? Or into next year?
A handful of tight races in some states make for the possibility that Election Day will come and go without deciding which party controls the Senate.
If that happens, brace for a fierce runoff election and possible recounts that could make for an ugly holiday season in politics and government.
The main reason for uncertainty: Louisiana’s election laws allow for a “jungle primary” in which all candidates, regardless of party, run in November.
Strategists in both parties say a Dec. 6 runoff is likely because Democratic Sen. Mary Landrieu and top Republican challenger Bill Cassidy will struggle to exceed 50 percent on the crowded Nov. 4 ballot.
Republicans need six more seats to claim a 51-49 Senate majority. A 50-50 split would let Vice President Joe Biden break tie votes and keep Democrats in charge.
Republicans are strongly favored to win three races where Democratic senators are retiring: West Virginia, South Dakota and Montana.
Their best hopes to pick up three more seats are in the four contests where Democrats seek re-election in states President Barack Obama lost: Alaska, Arkansas, Louisiana and North Carolina. Republicans are also making strong bids in Iowa, Colorado and New Hampshire.
If Republicans win two of those races, plus the three where they are heavily favored, then all eyes and lots of campaign money would turn to Louisiana if there’s a runoff.
“And I don’t think there’s any chance we don’t go into a runoff in Louisiana,” said Brian Walsh, a GOP adviser in Senate races.
Waiting for a make-or-break Louisiana outcome would deeply affect the post-election congressional session, when lawmakers must appropriate money to keep the government running.
