Republicans’ tough Senate map gets another twist

WASHINGTON (AP) — Republicans' plans to defend their Senate majority in 2016 just got a bit more complicated.
GOP Sen. David Vitter's loss in Louisiana's governor's race over the weekend, and his decision to leave theSenate next year rather than seek re-election, creates an open seat that Republicans will have to defend. It's a deep-red Southern state and the GOP will be heavily favored, but Democrats hope they might have a shot, especially with a newly elected Democratic governor, John Bel Edwards, as an unanticipated asset.
