This year's midterm elections have brought a wave of veteran candidates, and experts say if they win their seats it could bring more bipartisanship and foreign-policy oversight to Congress.

More than 200 veterans were vying for House and Senate seats this election season. Dozens of those candidates will now duke it out on Tuesday in some of the country's most hotly contested races.

The nonpartisan Cook Political Report identified 73 House and 14 Senate races that are likely to be highly competitive this Election Day. Of those races, 28 will have veterans on the ballots.

"Statistically, it's interesting to me, since we've moved to an all-volunteer force, that we're seeing so many veterans run compared to the percentage of Americans who serve," said Danielle Lupton, a political science professor with Colgate University in New York. "But veteran status is often an asset on campaigns. It can lend credibility, a sense of character and willingness to serve."

Ellen Zeng, the political director for With Honor, a cross-partisan organization that has endorsed 20 Republican and 19 Democratic veterans running for the House, said there are strong candidates who would bring a fresh approach to Washington politics. The veterans they've endorsed, six of whom are women, come from a diverse background and have signed With Honor's pledge to serve with integrity, civility and courage.

"There's something about this group of people," Zeng said. "They want to do things in a different way. They want to serve with integrity and serve across the aisle."

Aside from their time in uniform, the candidates have served as teachers, small-business owners or pastors, she said. They show a commitment, she added, to putting country before party.

Data also shows that veterans in Congress, regardless of party, are more likely to hold the commander-in-chief accountable when it comes to sending troops into harm's way, Lupton said.

Her research has shown that veterans use their military expertise, which civilian members of Congress might lack to sharply question any use of military force. They also request more data about ground conditions troops could face.

Here's a look at some of next week's races that could send more veterans to the Capitol.

SENATE RACES

In the Senate, there are three tight races with veterans on the ballots. In one of those, two veterans will face off against each other.
