Using the 25th Amendment to remove Trump from office is a temptation that must be rejected. It would clearly be a political move meant to extract from public life an unpopular figure. The United States of America cannot go down the road of confusing political unfitness with medical unfitness. The cabinet would simply be using the 25th Amendment as a pretext for taking down a lawfully elected leader they oppose. It would amount to an unconstitutional coup. If the 25th Amendment could be deployed in his case, it could be deployed in many other cases. How many times did their political opponents declare that Nixon or Reagan was “a lunatic” unfit to serve?
No, the Constitution is clear about the remedy for a president who has become politically untenable: impeachment and removal. The House of Representatives could easily pass articles of impeachment declaring that the president has violated his oath of office by attempting to subvert the election results and by sedition. Most Republican senators are probably too lacking in courage to consider removal, but only 17 of them need to come on board, assuming all 50 Democrats agree. Many key Republicans, such as Ben Sasse, Lindsey Graham, Mitch McConnell, and Susan Collins, do not face the voters for six years, by which time Trump can be ancient history, if they choose to make him so. A process of impeachment, removal, and disqualification from office would render it impossible for Trump to run for president again. This ought to be an immensely attractive prospect for the Republican Party. If Trump is reduced to being just another cable-TV blowhard hawking vitamin supplements and reverse mortgages, the threat he represents to Republicans will be contained.
