California Republicans will launch a campaign on Friday to convince conservatives to trust the state’s mail-in balloting system, hoping to boost turnout in the election to recall Democratic Governor Gavin Newsom, party officials said.

The party will roll out videos on its digital platforms showing Republican Party officials mailing their ballots and urging supporters to vote early in the Sept. 14 election, according to footage seen exclusively by Reuters and interviews with party leaders.

Polls show Republicans are highly motivated to vote in the election to recall Newsom, a liberal Democrat who has faced criticism over his policies on COVID-19, immigration and crime. But they have been turning in early ballots at half the rate of Democrats, who outnumber Republicans in California more than two-to-one.
