Updated, Wednesday 7:00 a.m. | The accidental congressman 's tenure in Washington came to an end Tuesday evening, when Michigan Rep. Kerry Bentivolio lost the Republican primary to attorney David Trott in this district northwest of Detroit.
Trott had 66 percent of the 11th District vote when The Associated Press called the race for him. Bentivolio trailed with 34 percent of the vote at that time.
Trott spent heavily on his own campaign and secured significant support from Michigan Republicans for his effort to oust the incumbent.
Bentivolio is the third incumbent to lose in a primary, following Reps. Ralph M. Hall, R-Texas, and Eric Cantor, R-Va. To see more on this, check out Roll Call's Casualty List . Former State Department senior adviser Bobby McKenzie narrowly captured the Democratic nomination. His margin over Democratic rival Anil Kumar was so narrow — 471 votes — The Associated Press didn't call the race until 100 percent of precincts had reported.
The general election is rated Favored Republican by the Rothenberg Political Report/Roll Call.
Michigan's 3rd District
Unlike Bentivolio, Rep. Justin Amash prevailed Tuesday in his Republican primary, holding onto his seat for a likely third term.
The AP called the race with 56 percent of precincts reporting, Amash was ahead 56 percent to 44 percent over former East Grand Rapids School Trustee Brian Ellis.
Some of the party's most powerful business groups, including the Chamber of Commerce, endorsed his opponent. But Amash's name recognition and support from tea party groups carried him over the line.
The congressman had 55 percent of the vote when Ellis conceded the race to him, per local reports.
Amash's antagonists were closely watching the margin — saying if it was narrower than 10 percent, they could go after him again in a future cycle.
The 3rd District is rated Safe Republican by the Rothenberg Political Report/Roll Call.
Michigan's 4th District
Republican state Sen. John Moolenaar is the all-but-certain successor to House Ways and Means Chairman Dave Camp in Michigan's 4th District, which stretches north from Lansing.
Moolenaar had 51 percent of the vote when the AP called the race with 73 percent of precincts reporting, while businessman Paul Mitchell trailed with 38 percent.
The state lawmaker was vastly outspent by Mitchell, who loaned his campaign nearly $3.2 million.
The general-election race is rated Safe Republican by the Rothenberg Political Report/Roll Call.
Michigan’s 8th District
Former state Senate Majority Leader Mike Bishop won the GOP nomination to replace retiring GOP Rep. Mike Rogers in the 8th District. He will face Ingham County Treasurer Eric Schertzing, who prevailed in a close Democratic primary.
Bishop had 60 percent of the vote with all precincts reporting, topping Tom McMillin, who took 40 percent.
Schertzing won with 43 percent of the vote, followed by Susan Grettenberger with 38 percent.
The race is rated Leans Republican by the Rothenberg Political Report/Roll Call.
Washington’s 4th District
Two Republicans advanced from the all-party primary Tuesday in the race to replace retiring GOP Rep. Doc Hastings in Washington's 4th District.
Former NFL player Clint Didier led the crowded field with 30 percent, followed by former state Agriculture Department Director Dan Newhouse with 27 percent. Finishing a distant third was Democrat Estakio Beltran, a former congressional aide, with 11 percent.
In Washington primaries, the top two head to the general election regardless of party.
The general-election race is rated Safe Republican by the Rothenberg Political Report/Roll Call, a rating made even easier with two Republicans advancing.
Too Close to Call
The Democratic primary in Michigan's 14th District was still too close to call as of 7:00 a.m. Southfield Mayor Brenda Lawrence led state Rep. Rudy Hobbs by nearly 2,500 votes with 100 percent of precincts reporting in the race to replace Rep. Gary Peters.
The two Democrats swapped the lead several times throughout the course of Tuesday night, and both had about 36 percent of the vote.
What is clear is ex-Rep. Hansen Clarke will not be returning to Congress. He trailed with 27 percent.
The district is rated Safe Democratic by the Rothenberg Political Report/Roll Call. The eventual nominee is almost certain to hold the seat for the Democrats in the fall.
