The race to fill the House seat that has been vacant since Republican Rep. Ken Buck of Colorado resigned in March is one of a handful of elections Tuesday with no incumbents on the ballot.
Buck’s departure caused a ripple effect when Republican Rep. Lauren Boebert decided to run in his district, leaving her own seat open. But Boebert is not running in the special election for the remainder of Buck’s term, which is being held at the same time as the primary for a full term. Colorado also has primaries to pick nominees to replace retiring Republican Rep. Doug Lamborn.
In Utah, Republican Sen. Mitt Romney’s retirement drew Rep. John Curtis into the GOP primary to succeed him, leaving Curtis’ seat open. And South Carolina is holding a runoff for the Republican nomination to succeed another retiring House member.
