Dozens of Republicans have signed an open letter urging Republican National Committee Chairman Reince Priebus to shift resources away from the Trump campaign to House and Senate races instead.

According to a report by Politico, the letter urges the RNC to shift resources to vulnerable congressional races in order to “prevent the GOP from drowning with a Trump-emblazoned anchor around its neck.”

“We believe that Donald Trump’s divisiveness, recklessness, incompetence, and record-breaking unpopularity risk turning this election into a Democratic landslide,” the letter reads, according to the report, which urges “the immediate shift of all available RNC resources to vulnerable Senate and House races.”

“This should not be a difficult decision,” the letter continues, “as Donald Trump’s chances of being elected president are evaporating by the day.”

The letter goes on to detail “outrages” which have “alienated millions of voters of all parties,” ranging from Trump’s attacks on the Khan family to his call for Russia to release Democratic opponent Hillary Clinton’s emails and his proposed ban on Muslim immigration. Among the more than 70 signees are former RNC staffers and former congressmen.

Republican Andrew Weinstein, one of the letter’s organizers, said that the letter is from “people who want the party to protect its majorities in the Senate and the House” but is ultimately “not an endorsement of anybody.”
