WASHINGTON (AP) — Incumbent lawmakers in Kansas, Michigan and Missouri are trying to fend off primary challengers while voters in Washington state are considering a replacement for a two-decade veteran.
Voters on Tuesday pick candidates to appear on November's ballots, and if recent contests are any guide, turnout will be low.
In Kansas, three-term Republican Sen. Pat Roberts faces Milton Wolf, a radiologist, tea party favorite and President Barack Obama's second cousin.
In Michigan, two establishment-minded Republicans were drawing on their own deep pockets in hopes of upending incumbents who often side with the tea party.
In Missouri, five incumbent House members face underfunded primary challenges.
And in Washington state, voters are considering 12 candidates vying to replace Rep. Doc Hastings, a Republican who is retiring.
