Democrats are complaining that Republicans are interfering in their primaries in congressional races across the country. Evidently, they forgot that they did exactly the same thing in GOP primaries just four years ago.

Democrats are unhappy with Republicans and GOP-aligned groups for boosting more beatable Democrats in primaries in California, Texas, Maine, Pennsylvania, and Nebraska, among others. This is typically done through ad campaigns or mailers that treat the more radical, beatable Democrats in the race as the Republicans’ chief opponent, signaling to Democratic voters which candidate the GOP is “scared” of in hopes of getting those voters to boost that candidate through the primary.
