Veteran Republican Lugar loses Ind. primary

WASHINGTON (AP

Veteran Indiana Sen. Richard Lugar lost a bitter challenge from the right flank of his own Republican Party Tuesday night, his nearly four-decade career in the Senate ended by a tea party-backed GOP foe.

Also Tuesday, North Carolina voters weighed a gay-marriage ban and Democrats were picking a nominee to challenge Republican Wisconsin Gov. Scott Walker in a June recall election, contests that overshadowed Mitt Romney's unstoppable progress toward the GOP presidential nomination.
