Proving he is not the right leader/man for this position.
A leader wanting to serve his fellow man would have stepped down after failing the first time and surely the second. But 3 votes he has failed and still hasn’t stepped down.
IDK much about McCarthy as a person, but you are right, his behavior reeks of personal power-seeking. During the last election his contribution to the cause was a really flabby pale imitation of Gingrich’s Contract with America. He unveiled it one day and it sank without a trace, never to be seen or heard again.
