Democrat politicians (and some that are not pols) are like that sneaky, backstabbing Eddie Haskell kid you see on Leave it to Beaver, just with much more bile. They completely destroyed "play-by-the-rules" politicians like McCain and Romney and used the complicit media to make it all seem valid.
Then you have Trump, who just walks right up and kicks them square in the nuts with no regard for niceties. So the sneaky kid is revealed for the complete bastard that he is, while Trump says the underhanded part right out loud, and it just breaks Eddie's mind. That's how you end up with Pelosi ripping up his speech.
I prefer decorum to what Trump does. Having said that, he deconstructs and ruins leftists like no one I've ever seen because he goes on the offensive constantly and they despise him for it.
