Trump will be a lame duck immediately.
Back in my yout, media proclaimed the same thing one minute after midnight of Reagan’s re-election. Congress worked hard to keep him in check. Never happened with bho though. However, as I look at bho’s legislative accomplishments ... other than obamacare, all his gains were through regulatory agencies and EOs. I expect you are right, if Trump were elected in 2024, the lame duck will be a clarion call of the leftist media to make him a lame duck.
The reality is he cannot do it himself, and unless the GOP has a real awakening, how far he can go without Congress will be limited. But as long as he has 34 - 40 Senators who won’t break rank, he can be effective with his veto pen, grinding things to a halt in DC might be a good thing.
They've had their awakening. The problem is that they have not realized that the counterawakening they launched has fizzled out and they are as reviled as the picture in post #7.
