Durant ran ads attacking Hoesktra as holding similar positions to Stabenow, including his support for the TARP bailout, while painting himself as an outsider. A super PAC also ran ads on his behalf in recent weeks, and he reeled in some big-name endorsements in the final month, including from the Tea Party Express and former presidential candidate Mike Huckabee.
But it wasn't enough to close the gap with Hoesktra; polls never showed him within striking distance of his opponent.
In a statement after the election was called, Durant called for people to unite around Hoestra.
"Going forward, I will continue to be a 'Rebel With a Cause,'" said Durant. "This is about fighting the status quo in Washington of record debt and record spending which has pushed this country to the brink of fiscal disaster."
