But why? Has Trump promised vast sums to those who support him? Does the Republican Party believe he's going make huge donations as long as he's not impeached?
If they're doing all this just to maintain the support of those who support Trump and wouldn't otherwise support the party, then they must acknowledge that the party is, for all intents and purposes, about to die either way and all of this is to steal what they can before they're all voted out of office.
If, on the other hand, they're doing this because Trump has made any promises to them, then they are literally the dumbest, most gullible people on the planet. The second Trump leaves - or is dragged out of - office he will burn every remaining bridge and stiff anyone to whom he made promises.
On that level, it's kind of amazing that they don't want Pence to take over. He's so whipped that he'd do anything the party asked and probably call the person passing the orders "mommy."
Then again, maybe Pence is so whipped that he's informed McConnell and scum that if Trump is kicked out office he'll resign and leave Nancy Pelosi to take over the Oval Office. ****. That's actually plausible to me right now.
