Nebraska Senate race surprise: It's "more competitive than it should be"

Washington — In a cycle that appears to be exceedingly favorable for Republicans hoping to take control of the Senate, one seat representing a Republican stronghold is facing a surprising challenge this November. 

Independent Dan Osborn is running an unexpectedly competitive Senate race in deep-red Nebraska in his bid to unseat two-term Sen. Deb Fischer in a race that could shake up the fight for control of Congress' upper chamber. 

Osborn, a Navy veteran, mechanic and union leader, has been garnering millions of dollars in outside support and prompting Republicans to redouble their efforts in a race that was thought to be an easy win.
