Prominent Donald Trump supporter Sean Davis hit out at Republicans - and the president himself - in a scathing takedown on X over the weekend.

Davis, CEO and co-founder of the conservative website The Federalist, called out whoever "is advising congressional Republicans on strategy right now," saying they have "an IQ barely approaching room temperature."

"Republicans right now have no accomplishments, no plans, and no vision," he said, asking, "Why on earth would anyone be excited to go vote for them 12 months right now?"

"Trump needs to ditch the foreign policy crap and focus all his attention on the domestic economy, which is still not working for the majority of people," he said. "Right now he looks weak and rudderless. Be mad all you want, but it`s the truth."

Davis railed: "You cannot have a viable country or future when half your country and all its young people are locked out of the economy and locked out of ever owning a home or much of anything beyond next month`s streaming subscription."

"Does anyone in Washington care about this? Anyone at all?" he asked, before signing off with a warning for his party.

"Republicans had better wake up, because right now their nightmare is only beginning if they don`t start making massive changes," he said.

Davis is one of a few conservative voices speaking out to criticize some of the recent choices Trump has made.

The Wall Street Journal`s editorial board, which has repeatedly criticized the president`s economic policies, condemned Trump`s announcement to give Americans a $2,000 dividend from his tariff policy revenues in a piece released Sunday.

"We`ve advised Mr. Trump from the beginning that tariffs would do economic harm, and so they are," the Journal`s conservative editorial board said. "They`re also doing political damage to the GOP, which is why he`s floating rebates that contradict his other tariff claims."

Rep. Jeff Van Drew (R-N.J.) also raised the alarm over the weekend, saying the GOP will "get killed" if they don`t take voters` health care affordability concerns seriously.

"It`s about winning. We have to win the midterms," he said during an appearance on Maria Bartiromo`s Fox Business show on Sunday. "It`s going to be a hell of a hard thing to do, and if people are just struggling with their health care, it`s not going to help us."
