Voters in Oregon's 1st Congressional District on Tuesday will be deciding who should fill the remaining term of former Rep. David Wu, D-Ore., who resigned following accusations he had made unwanted sexual advances on the teenager daughter of a campaign donor and friend.

Former state legislator Suzanne Bonamici, a Democrat, is facing sports marketing businessman Rob Cornilles in the special election.  Wu resigned his seat in August.

Oregon’s 1st Congressional District is a big and diverse one that extends from the west side of the Willamette River in downtown Portland to the Silicon Forest in Washington County to the north Oregon coast.

Cornilles, a Republican, said he'd bring bipartisanship to Congress. "I think that people are really ready for a bipartisan attitude in Congress. They're so sick of both sides being so entrenched and unwilling to kind of meet in the middle, wherever the middle may be," he said.

Bonamici said she believes she has the support of Democrats, Republicans and independents because her message is one “of accomplishment, of getting people back to work.”

In Portland, FOX 12 political analyst Tim Hibbitts said polling of voters reflects the difference in voter registration in the First District.

"It's is a Democratically leaning district," Hibbitts said. "It is not impossible that Rob Cornilles could pull off an upset, but it's a real long shot. It's got a 10 or 11 percent Democratic registration edge. Polls have suggested the lead has pretty consistently stayed around 10 percent."
