Tight races lead to higher voter turnout, says Morning Consult editor

Voters are more energized about casting ballots in tight races, leading to higher turnout on Election Day, according to Morning Consult executive features editor Anna Yukhananov.

"I think there's definitely evidence that when races are very close, more people feel like their vote matters, and they're going to show up to the polls," Yukhananov said Friday on told Hill.TV's "What America's Thinking."

"That's not the case for every case in the nation, but certainly some of the hotly contested ones," she added.

Studies show that a race's competitiveness affects voter turnout.

Sixty-six percent of eligible voters cast ballots during the 2012 presidential election in the 12 most competitive states, according to FairVote.Org. Meanwhile, 57 percent turned out in the 39 other states and Washington, D.C., according to FairVote.

Candidates are making their final pitches to voters in competitive districts and states, with the Nov. 6 midterm elections less than three weeks away.

The nonpartisan Cook Political Report rates four Senate races in Democratic seats -- Florida, Indiana, Missouri and Montana -- as "toss-ups," along with four races in Republican seats--Arizona, Nevada, Texas, and Tennessee. 

The report also rates three Democratic House seats and 46 Republican House seats as "toss-ups."
