COLUMBIA, S.C. (AP) - More than halfway through a tumultuous primary season, voters have rendered verdicts in a number of contests, many of which featured candidates arguing they best represented a continuation of policies favored by former President Donald Trump.

While not on the ballot himself, Trump has played a role in several races, with candidates bearing his endorsement meeting a variety of electoral outcomes. There have also been tumbles by several incumbents, some taken out by Trump-backed challengers and others bested by fellow representatives in faceoffs forced by redistricting.

Here's what's happened so far in primary races across the country:

FALLEN INCUMBENTS

Eight incumbents - three Democrats and five Republicans - lost their U.S. House seats already this year after being defeated in their primary elections.

Four of those losses came in incumbent-on-incumbent races, a result of the once-a-decade redistricting process.
