These Republicans likely made a deal with the totalitarian heathen that have perfected the “art of the steal.” It now does not matter what letter is before your name if you promise to go along and get along. Their seats. are now safe for all practical purposes.
Some of those Republicans who voted to impeach may have their eyes on Senate/ Governor seats in blue states. They may believe by voting to impeach they will have a better chance.
There were times when Leon Trotsky and Ernst Röhm thought their seats were safe.
There is no way that the hard left will tolerate them once they feel the revolution is secure. They are at greater risk than we are.
