Texas businessman Doug Deason, a Trump backer and the son of billionaire Darwin Deason, said he and other major GOP donors were warming to the idea of funding primary challenges to senators who had opposed the health care bill. There was growing frustration, he said, over the failure to advance the president’s agenda.

In a text message referring to three senators — Sens. Susan Collins, Jeff Flake and Shelley Moore Capito — who played a role in sinking the bill, Deason ripped “the spineless Republican members from Maine, Arizona and West Virginia who seem to believe that Obamacare is actually succeeding.”

He added: “It will be disappointing to see these three lose their reelection campaigns to Democrats — unless we can find better candidates to run in the primary races against them.”
