Thirty-five states will have held primaries after today’s elections in Kansas, Michigan, Missouri and Washington state.
In Michigan, Republican Rep. Kerry Bentivolio faces a big-spending challenge from lawyer David Trott in the 11th District near Detroit. Bentivolio won the seat in 2012 after the incumbent, Rep. Thaddeus McCotter, resigned following a ballot-signature scandal.
In the Grand Rapids area, Republican Rep. Justin Amash, a favorite of Tea Party activists promoting limited government, faces a well-financed challenge from businessman Brian Ellis that’s been aided by the federal, state and local chambers of commerce. See previous Bloomberg coverage on that race here and here.
Republican Reps. Dave Camp and Mike Rogers and Democratic Reps. John Dingell and Gary Peters aren’t running for re-election, and the winners of the defending party’s primaries will also be favored to win in November.
Dingell, first elected to the House in 1955, is the longest-serving member of Congress in history. His wife, Debbie Dingell, who’s long been active in Michigan civic and political life, is highly likely to succeed him.
In Kansas, Republican Sen. Pat Roberts is opposed by Milton Wolf, a radiologist with some support from Tea Party-aligned groups. In the Wichita-area 4th District, Rep. Mike Pompeo is opposed by his House predecessor, Todd Tiahrt, who represented the area from 1995 through 2010.
The next primary is Aug. 7 in Tennessee, where Sen. Lamar Alexander’s top challenger, state Rep. Joe Carr, has attacked the incumbent’s vote last year for an overhaul of immigration laws. Republican Rep. Scott DesJarlais is laboring to keep his 4th District seat after ethical troubles surfaced in 2012.
On Aug. 9 in Hawaii, the big race is between appointed Democratic Sen. Brian Schatz and Rep. Colleen Hanabusa.
