An anti-Trump Republican group is planning to spend $50 million in a campaign to stop the former president from winning a second term in the White House.

Republican Voters Against Trump plans to share testimonial videos of Trump’s past backers who will share why they won’t be supporting the former president come November.

The campaign is orchestrated by Sarah Longwell, a Republican strategist who has long been critical of Trump. The plan is to target “moderate Republican” and Republican-leaning voters in swing states with videos. The group had a similar strategy in 2020, when they shared more than 1,000 testimonials during an election that President Biden won.
