McCarthy may have survived the day, but Senate Republicans and some House GOP moderates are freaking out.

Rep. Don Bacon of Nebraska, who holds one of the 18 Republican seats Biden won in 2020, stated a novel concept: “I think an inquiry should be based on evidence of a crime that points directly to President Biden," he said.

"[W]hat crime has the president committed?" Bacon wondered. "[W]e should dig that stuff up before we go down this path,” he added.

Other “Biden 18” members struck a more optimistic note on the question of due diligence.

“I think we’ve got enough substantiation for it to move forward, we’ve got critical mass,” said Rep. Mike Garcia of California, who represents a district Biden carried by double digits in 2020. “What I tell my constituents is we seek clarity, right, I think that’s what most Americans want is clarity. So let’s go get all the facts and data behind it."

Polling of voters in the 18 Biden districts suggests Garcia's rationale is going to be a tough sell. A Public Policy Polling survey of Biden 18 voters conducted last month found 56 percent thought opening an impeachment inquiry into Biden would be a "partisan political stunt," while just 41% said it would be a serious effort to investigate important problems. Fifty-six percent also said they thought opening such an inquiry would be more about damaging Biden politically than finding the truth, compared with 41 percent who said the opposite. In both instances, that yawning 15-point chasm should be a flashing warning sign to a Republican in enemy territory.

While some House Republicans, including the speaker, don't seem particularly concerned about risking their majority next year over a baseless inquiry, Senate Republicans spent the day breathing into a bag.

“It is frustrating, obviously,” Sen. Shelley Moore Capito of West Virginia told The Hill. “I don’t know what the evidence is, where they’re going with this. I’m going to default to the position that the House is going to do what the House is going to do, and we’ll have to react to that.”

And one GOP senator who was granted anonymity to speak on the matter gave The Hill an earful. “Maybe this is just Kevin giving people their binkie to get through the shutdown,” the Senate Republican said.

Calling the inquiry "a fool's errand," the Republican senator added, “It seems like we’re spending a lot of time on things that matter to them that don’t matter to the people I want to have a positive opinion of Republicans next November."

The GOP senator concluded, "It doesn’t do anything to help us with our campaigns next year."

Nope, it sure doesn't.
