Which one is not a reason a president can be impeached treason bribery high crimes unpopular with the opposing party

Unpopularity with the opposing party is not a valid reason for a president to be impeached. It is important to note that impeachment is a constitutional process used to remove a president from office for specific reasons such as treason, bribery, or high crimes and misdemeanors. Unpopularity, although it may be a factor in political dynamics, is not a legal basis for impeachment.
