It is not that they don't want to stop the Trump assault on the deep state, they know that arrests and charges are coming and need to appear to be on the right side.
Absolutely. The wise RINO is currently keeping a very low profile. It helps them in that the most overtly insane or corrupt among their kind -- Liz Cheney and others -- have flown the GOP coop to pretty much openly become the leftists they always really have been.
Yes, the Right has been trying to 'clean' the GOP house for decades. The Left cannot even conceive of getting rid of their corrupt politicians FOR being corrupt.
IN OTHER WORDS VOTERS APPROVE THAT RINOS ARE NOT OVERTLY TRYING TO THWART TRUMP'S EFFORTS TO CLEAN UP THE CORRUPTION THAT THEY AND THEIR LEFTIST POLITICAL ALLIES ALLOWED TO OCCUR ON THEIR WATCH.
