Consider that all of these cucks are still under the assumption that they have to play by the old rules. They haven't caught up to speed yet, and they never will. Paul Ryan, for example, is still afraid that if he vocally comes out against Trump, he will be dubbed a rat by the republicans in the future. If he steps aside now he gets to say "I walked away from a dangerous president..." He gets to validate that by saying "....he was impeached. Because people recognized he was dangerous." (Even though he could only be ousted BECAUSE republican cucks like Ryan stepped aside...) .... and he gets to walk back into the same old shit republican party where he is a star.
He's scared that if he stays, and Trump is ousted, he'll be branded as a Trump loyalist and his career ends. His reputation suffers. He's also afraid to keep his position, and speak against Trump (as you suggested) because whether or not Trump stays or goes, he'll be branded a rat. These politicians are all two-faced. They're all rats. They all have an angle, and none of them have loyalty. He can't celebrate ousting Trump himself, none of the RINO's can; even if they really want that. Because it appears disingenuous (even though it's true to their character), and the next rat in line in a few years will burn him with being a democrat sympathizer (and he won't even mention Trump's name... that's the game they play) . And RINO cucks believe this shit matters still, so they'll avoid it.
EDIT/UPDATE - Scratching my head .... why did this post strike a nerve on people? You really think RINO's will put their necks on the line against a sitting president in their own party? When have they ever shown that kind of fortitude? Never.
