Anyone suggesting the 25th is a complete fucking moron.
The 25th Amendment requires the following:
1. The VP to convince half of the cabinet to remove the POTUS.
2. The POTUS can ask Congress to reinstate him.
3. Unless 2/3rds of the House and 2/3rds of the Senate agree, the POTUS is restored.
Compare the above to a simple impeachment plus removal
1. 1/2 of the House has to agree to impeach him.
2. 2/3rds of the Senate has to agree to remove him.
This is basic math, don't mainline hopium.
