Republican Senator Richard Lugar as held the Indiana’s Senate seat since 1976, but with Lugar retiring, the possibility for a Democratic coup has become possible. After Republican State Treasure Richard Mourdock’s comment that pregnancies resulting from rape were “a gift from god” at the Oct. 23 debate, Democratic Rep. John Donnelly has looked to capitalize on the situation.

The result will help determine control of the U.S. Senate, where Republicans need only three or four seats to gain control if some other expected seats turn.

Associated Press reports that some Indiana voters stood in line for over three hours to cast their vote. Voting has remained heavy across the state despite early voting over the past month in which more than 520,000 people voted.  

Voting in Indiana was also hindered as a programming glitch hit voting machines in about half of the county’s polling sites. This delayed the start of voting by about 20 minutes, said Hamilton Country Election Administrator Kathy Richardson.

Despite the glitch, Richardson attributes the long wait to the volume of people coming out to vote.

"We didn't get off to a good start, but when you have two-hour lines and you only had a 20-minute delay, the delay wasn't the problem," Richardson said. "The volume of people who have come to the polls is what's causing the issue."

The delay has also deterred some voters from casting their ballot. Associated Press reports that there were many sightings of people leaving their place in line before they reached the voting machines. 

Indiana polls closed at 6 p.m. Eastern Standard Time.
