I'm not really sure they're thinking at all.
Actually, they are, but not in the manner of rational thought.
Their idea here, I think, is to make impeachments meaningless.
Roger Ailes et al. were so pissed about Nixon they started Fox News.
That's how we ended up with White Water, Kenneth Star, etc.
The republicans wanted revenge.
Now that it's happened twice to Trump they want to remove the stigma of impeachment.
They don't need any, you know, proof, they just need it to happen to make Trump's two impeachments look like "no big deal".
It's impeachment season? We can do that too y'know. Schmear campaign anyone?
O.k. the clown show is about to get absolutely crazy.
