House races to watch during midterm elections

Republicans hold the majority in the U.S. House – but Democrats are hoping to ride a “blue wave” in the midterm elections to take back control.

There are dozens of House races in the midst of contentious and close battles across the country that could make or break it for Democrats this year – including several GOP-held seats in California that are no longer a shoo-in for the Republican Party.

Read on for a look at 20 House to keep your eye on during the midterm elections.

Longtime GOP Rep. Dana Rohrabacher has been a polarizing figure in Congress, where he’s served since 1989. Although it endorsed him, Rohrabacher’s hometown newspaper said he “has a tendency to say wildly inappropriate things” and has “an affinity for Vladimir Putin.”

Rohrabacher faces Harley Rouda, an Orange County businessman, in the race which Fox News has ranked a toss-up. The election is one of the nation’s most costly this year, which former New York City Mayor Michael Bloomberg spending more than $4 million in support of Rouda.

Embattled Rep. Duncan Hunter is locked in a tough re-election fight against Democrat Ammar Campa-Najjar. Fox News has ranked the race as leaning Republican.

Republicans have harped on Campa-Najjar’s family throughout the race, and Hunter has said he is a “national security risk” because of his ties to Palestine and his grandfather’s involvement in the 1972 Olympics terrorist attack, The San Diego Tribune reported.

Campa-Najjar, who was granted a federal security clearance when he worked in the Obama administration, has admitted his grandfather “was associated with something that was heinous, that was wrong and he was brought to justice.” He also disavowed “the murder of innocent people.”

Hunter, too, isn’t without his controversies. He and his wife were indicted earlier this year on charges of illegally converting $250,000 in campaign funds for personal expenses and filing false records, prosecutors said. Hunter has brushed off the allegations as “pure politics.”

Shalala is the former Health and Human Services secretary under the Clinton administration and president of the University of Miami. She faces Republican Maria Elvira Salazar, a Spanish-language journalist, in the race to replace retiring GOP Rep. Ileana Ros-Lehtinen.

Fox News has ranked the race between Joe Radinovich, a former state lawmaker, and Pete Stauber, a former county commissioner and veteran, as leaning Republican. Except for a brief, two-year period in 2010, the seat has remained steadfastly blue since the late 1940s.

It’s an election poised to make history no matter who wins New Hampshire’s 1st congressional district.

And Democrat Chris Pappas, a former state lawmaker, would be the state’s first openly gay congressman.

Republican Rep. Pete Sessions has been in Congress since 1997, representing what is now the 32nd congressional district since 2003. But the longtime congressman’s seat appears to be in jeopardy this year as he’s locked in an expensive re-election campaign against Democrat Colin Allred.

Fox News has ranked the race as a toss-up. Sessions didn’t face a Democratic challenger in 2016 – but his district turned blue for Clinton over Trump.

A civil rights attorney from Dallas, Allred said he was “inspired” by the “many grassroots voices” that have emerged since the 2016 election. He is also a former NFL player who played for the Tennessee Titans. He’s drawn on his upbringing – raised by a single mother and their community – throughout his campaign, according to the Dallas News.

Virginia 10: Barbara Comstock vs. Jennifer Wexton

Rep. Barbara Comstock was first elected to represent Virginia’s 10th congressional district in the U.S. House in 2014. She won re-election once in 2016, but this year her seat is in jeopardy as she’s considered one of the most vulnerable Republicans in Congress.

Fox News has ranked the race between Comstock and state Sen. Jennifer Wexton, a former prosecutor, as leaning Democrat. A Republican has represented the district for more than three decades.
