The thing I’d count on if Pence was instated, is that people don’t like to lose their sense of power.
Think: balance of power at the Fed level. One might think “Oh, if you have a matched congress and president, everything is smooth for them”.
But reality seems to be Congress works towards their next term and sees the President as temporary.
So, they’d have to do things that didn’t appear that they were simply mirroring the President because if they did, they’d appear weak and copycats.
So even with a seemingly matched Pence+Congress, I’d expect the same kinds of battles you see now and always see.
And yes, I’ll take a Pence over Trump. Pence would not embarrass me in appearance. I’d expect a few more conservative years and some ridiculous things put into place that whoever follows, who would certainly be Democrat (because the flip/flip is normal), they’d overturn the worst of them.
