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.
