Country First is hoping to flood this year’s Republican primary with nontraditional voters, and its website has information about how to change party registration in all 50 states, plus deadlines for registering in time for the primaries.

Known as “party raiding,” a 2021 Princeton University Electoral Innovation Lab study of party registration in Utah found most people who became Republican ahead of the state’s latest primary were unaffiliated voters and not Democrats. Country First, however, sees the tactic as critical in defending Congress, as well as state legislatures and offices that administer elections, like secretaries of state.
