The House GOP’s push to impeach Joe Biden appears close to stalling out for good.

First, the impeachment of Homeland Security Secretary Alejandro Mayorkas scraped through on the narrowest of margins — and took two tries, raising serious doubts about Republicans’ appetite for an even bigger impeachment fight. Then, a high-profile informant making bribery allegations against the Biden family was not only indicted, but has now linked some of his information to Russian intelligence.

Even before those recent developments, the numbers were lining up against House Republicans, who can only afford to lose two votes on the floor after Democrats won a special election in New York. Falling short on a Biden impeachment would be yet another embarrassing bullet point for a conference that struggles to square the ambitious demands of its right flank with the reality of a thin majority.

“I happen to know there are like 20 Republicans who are not in favor of a Biden impeachment. Mainly because it smells bad what he did, it looks bad, but when you ask them what crime is committed — they can’t tell you,” said Rep. Don Bacon (R-Neb.), a vulnerable purple-district incumbent who'd raised doubts about impeaching Mayorkas but eventually backed that effort.

Bacon estimated that as many as 30 House GOP lawmakers may be currently opposed to impeaching the president because they haven’t seen evidence of any crime. Private briefings to update members on the investigation haven’t swayed those holdouts, and Republicans know it only gets politically riskier to try to impeach Biden as they head deeper into an election year — possibly giving the president a polling boost even if they succeed.

Oversight Chair James Comer (R-Ky.), in a TV interview after the party lost a special election in New York last week, said that the “math keeps getting worse” for impeaching Biden. Conservatives, however, are still hoping to eke out new momentum from next week's scheduled deposition of Hunter Biden and a March hearing with Special Counsel Robert Hur, who investigated Joe Biden’s mishandling of classified documents.

But members across the ideological spectrum acknowledge that recommending Biden's removal from office will be much harder than the previous vote on Mayorkas. They had hoped impeaching the Cabinet official would be an easy way to vent anger about Biden's handling of the southern border; instead, it became the latest warning sign that the GOP's so-far thin case against the president is going nowhere.

Asked if House Republicans would be able to impeach Biden after they initially failed on Mayorkas, Rep. Ralph Norman (R-S.C.) bluntly said “no.” Norman, a member of the conservative Freedom Caucus, added that the conference “should have been at 100 percent” on wanting to oust the Cabinet official.
