It is a three-horse race for the Republican nomination for Indiana's 2nd district, with Joseph Roush versus Tony Zirkle versus Luke Puckett.
The winner will go on to face Joe Donnelly. The Democratic incumbent is unopposed this primary.
Only one of those Republican candidates is getting backing from the St. Joseph County GOP, and that candidate is Luke Puckett.
NewsCenter 16’s Sarah Platt caught up with all three candidates on this Election Day, and all were hopeful that voters will support them.
Candidate Joe Roush claims he is the working person's candidate, and working his paper route was exactly what he was doing on Election Day.
“I'm hoping that there's enough people in the Republican party that are discontent with things and put me into Congress,” said Roush.
Candidate Tony Zirkle says he is the most educated and only veteran in the group and he is busy answering voter’s questions on his website.
“I’m trying to educate and inform people, trying to monitor my discussion room on my website today, trying to answer everyone that I can,” said Zirkle.
Meantime, candidate Luke Puckett has been hitting the pavement since early in the morning, talking to voters on the street and outside local polling places.
“We're focused on healthcare and getting prices down and accessibility up, as well as national security, allowing commanders to make decisions on when to get out of Iraq,” explained Puckett.
Again the winner of tonight's primary election will face off against Democratic incumbent, Joe Donnelly this fall.
Because of all the attention on the Democratic ticket, Republicans acknowledge that voter turnout is a bit of a concern. They are still hopeful their supporters will come out.
