Three GOP groups are spearheading an eight-figure vote-by-mail initiative in Pennsylvania to “ensure Republican victories” and encourage mail-in voting from conservative voters, a strategy that has long been championed by Democrats that could make a significant impact on the 2024 election.

The Keystone Renewal PAC, the Sentinel Action fund, and the Republican State Leadership Committee PAC announced the launch of the initiative on Tuesday, which they say is the largest vote-by-mail program in Pennsylvania. Mail-in voting has been a sore spot for Republicans, particularly as leaders such as former President Donald Trump have associated vote-by-mail with election fraud.
