Red_wiggler has my answer.
But seriously, what had people on board with Trump was “pwning the libs”, and so everything I’d do has to be phrased in that context. The speeches are formulaic.
“I’m the best at [topic]. I know a lot about [topic]. The dems don’t know anything and they’re trying to steal my [topic]. That thing they did, that doesn’t belong to [topic] at all. My thing? It’s the best, most beautiful thing ever. We’ll make America Great again, just you watch.”
Anybody noting how I’m acting differently will get brushed off as hating America or being jealous of how great of a Preznit I am. Anybody opposing my plan will have their credentials questioned and will also be assigned a juvenile, insulting nickname.
Now, while I’m talking all that talk and riling up my base, I’d just go ahead and enact a moderate, reasonable policy, and then aggressively deny everything as some kind of Democratic whinining because they hated how awesome I was. Let’s go build some yuge, beautiful roads. Let’s fix American’s bridges, because they’re the best in the world. The Democrats hate our big, beautiful NATO alliance. They resent how much awesome trade we’re doing. Trade wars are easy to win? Nah bro, TRADE is easy to win. Democrats want you all on welfare and I’m making all these awesome jobs. Wait’ll you see my Trumpcare, it’ll be the best ever. (It’s Obamacare but I sharpied out the name and wrote my own over it.)
What a ramble!
Anyway, all I have to do is keep my base riled up. I keep providing targets for the Five Minutes Hate. Any Republican daring to question my actions becomes the next target, and my enormous warchest can go to help my allies and weaken my foes.
They’ll stay in line. As long as I keep my base in a perpetual lather, I expect my party members would remain a bunch of spineless weenies more interested in being reelected and getting that graft than being any serious competition. A few bribes here and there may sort out the rest.
I’m already good at spouting off random, vaguely insulting crap. Now that I sound exactly like Trump, because I AM Trump, my impersonation is nearly foolproof. Trump will make the world an angrier place, because “my” base is blinded by their anger. I’ll make it a better place, and they won’t care about the provenence of it, because we’re pwning the libs.
(Though I guess it would make true social change harder. Well, if I piss everybody off enough, all the liberals will rise together and vote in an even older man than the body I’m in.)
