Jason Owen and Regina Smith will go head to head on primary day for a spot on the November ballot.
Smith has worked in both the public and private sectors.

Smith believes she's the most experienced candidate in the race.
"I've been behind the scenes and seen how government is supposed to work. I see the rights and the wrongs of it, so I'm looking forward to finding my own voice which is one of the reasons I'm running," said Smith, Republican Candidate for PA Rep. 3rd District.
Jason Owen is a bankruptcy attorney who has lived in Erie his whole life.
He says there are many factors that motivated him to run for State Representative, including his work on the save the 814.com petition, the issue of redistricting and funding cuts to the Flagship Niagara League, Owen believes the way these issues were handled shows there's no leadership in Harrisburg.
"You can talk a good game, but it's all about rolling up your sleeves and working hard for the citizens of Erie County and that's what we need is someone who's going to fight for us and be an independent voice for the 3rd district," said Owen, Republican candidate for PA Rep. 3rd Distrct.
Smith says you should vote for her Tuesday, because she is the most experienced candidate in this race and will be a voice for working families in the district.
"When I do go to Harrisburg, I'm gonna have that mindset, this is our money that we're dealing with and we can't just continue to tax people and throw more money at problems without some type of leadership and that takes into consideration those things,l" said Smith.
Meanwhile, Owen explains why he's the candidate for the job.
"Because we need a strong voice in Harrisburg, an independent leader who will fight hard for Erie County, roll up their sleeves, someone who can talk the talk as well as lead by example," said Owen.
