They are low and easily reachable.

In turn, a handful of House conservatives are offering McCarthy something more heated: threats to leverage a parliamentary weapon—reinforced by the speaker himself in order to secure the gavel—to force a vote on booting him from the gig he’d fought so hard to secure.

For now, few in the House Republican Conference are taking those threats all that seriously. The conservatives most upset with McCarthy are the same bunch who swore they were “Never Kevin” during the speakership battle in January, before they ultimately cleared a path for him after 15 excruciating rounds of voting.

But their frustration isn’t meaningless. It’s emblematic of the cracks in the foundation of McCarthy’s speakership—built on heaps of members who never thought he was the man for the job.

And if a debt deal that dozens of his own members couldn’t stomach isn’t the thing that kills McCarthy’s speakership, it will certainly have left him weaker. Unaddressed, the wound could fester into serious political pain for the GOP leader.

Ahead of Wednesday’s vote, the hard-right flank of the party didn’t hold back in spelling out the poor state of things. Asked by The Daily Beast if the deal would create long-term distrust between McCarthy and conservatives, Rep. Dan Bishop (R-NC)—perhaps the speaker’s most dogged critic this week—paused for a long time.

“He’s blown Republican unity to smithereens,” Bishop finally said. “So, you can put that in terms of trust, if you want to. It’s just something that is functionally destroyed.”

Pressed on whether he’d back a maneuver to oust McCarthy, Bishop didn’t rule it out.

“The important thing is how the Republican Party operates to serve the American people. And whether we do so in a unified fashion requires unity,” he said. “Unity has to be cultivated, forged, and then preserved… The responsibility for preservation falls to the speaker, and he has utterly failed in that.”

The good news for McCarthy is that it would take more than just one Republican to remove him from his position. The bad news is that it wouldn’t take much more than a half-dozen—if Democrats want to cooperate with the coup.

The slim GOP majority in the House means that McCarthy has very little wiggle room. And even if 95 percent of his conference is behind him, that last 5 percent could sink him.
