In total, there are 10 House races Democrats believe could be competitive in November. Trump won the district with 52%, and while Janz has raised quite a bit of money, the district is still considered safe for Republicans in November.
Significant contests also played out elsewhere on Tuesday.
Voters on Tuesday also went to the polls to choose candidates in primaries in Iowa, Mississippi, Alabama, Montana, South Dakota and New Mexico.
Early returns showed Republican Young Kim, a former Royce aide who won his endorsement, leading the field, followed by Democrat Gil Cisneros.

Republicans had feared that Democrats would win both of the governor's spots in California's unique top-two primary system.
Almost two-thirds of voters recalled Newman, of Fullerton, over his vote last year to increase fuel and vehicle taxes to raise about $5 billion a year for road repairs. But he was on the minds of many voters. Nick Freitas of Richmond, and 2013 Republican nominee for lieutenant governor and minister E.W. Jackson of Chesapeake... "They were separated by about 286,000 votes".
"I'm really, really anxious about our Constitution being ruined by this presidency", Karuntzos said after casting her ballot at a local community centre. It was a district Trump won in 2016.

Newsom, who now commands 33.3% of the vote compared to Cox's 26.2%, is most widely known for his early support and temporary city-wide legalization of same-sex marriage and for his early support of marijuana legalization.
Cox, who has largely self-funded his campaign for governor, decries what he calls the corrupting influence of special interests - a line of attack he's sure to deploy against Newsom, who is backed by heavy-hitting unions, businesses and interest groups. There are four districts in particular that they were targeting, and in all of them Democrats advanced candidates whom national Democrats see as the strongest candidates. Second place is far less certain. The party must wrest at least 23 seats from Republican hands.
National Democrats spent more than $7 million trying to curb and fix the damage inflicted by Democrats attacking each other in districts opened by retiring Republican Representatives Ed Royce and Darrell Issa, and the district where Republican Dana Rohrabacher is facing challenges from the left and the right. "The true debate within the Democratic Social gathering is whether or not it could be higher for Democratic turnout within the fall, for the home races, to have two Democrats on the poll or one Democrat and one Republican".

There are other kinds of drama playing out in other parts of the country.
In the House, things are looking better for New Jersey Democrats. Republican businessman Bob Hugin claimed the Republican nomination Tuesday and will face Menendez this fall.
Many of these women credit President Donald Trump's election and the potency of the Me Too movement with fueling their desire to run. In a fight against Newsom, his voice could force a more realistic and nuanced discussion as to how the state would pay for a single payer system, projected by some to require the state health care spend to double, and require Medicare and Medicaid waivers, which are not likely give the federal climate on health care. If Grisham wins, she'll be the state's second Latino state executive.
In Alabama, Gov. Kay Ivey, the state's first female governor, defeated three GOP challengers. Haaland, for example, served as state party chair before running for Congress.
