Key terms in this cycle's primary results

Incumbent primary loss: When a sitting member of Congress is defeated by a challenger from their own party before reaching the general election, removing them from the ballot in November regardless of how safe their seat might otherwise be.

Redistricting-forced matchup: A race created when new district boundaries place two incumbents from the same party in the same district, guaranteeing one will lose regardless of general-election outcomes — the situation Texas Republicans created for Johnson and Green.

Full details on the remaining primary results are available in the Guardian's original report.
