Trump has kept most to all of his promises that are within his control. Tucker’s point is that he doesn’t know how to deal effectively with the swamp politicians to get the big permanent things he wants that they are reluctant to give him. For example he doesn’t know how to twist their arms like Johnson, Obama or some others did to get their way. Sending tweets and making public statements certainly haven’t moved the politicians much. They only gave in on the tax uts because their business donors BENEFITTED, much more than individuals.
Carlson isn’t a liar. He certainly is not considered ignorant by anyone. He may say things you don’t like or agree with. So do we all.
As for gop turnout, the conservatives rightly didn’t want to reward a do nothing, not trump supporting congress led by dirtbags like Paul Ryan. They were not going to reward those clowns for their foot dragging. At the same time the anti trump forces were at an all time high energy caused by constant anti trump publicity.
First of all, LBJ was ruthless and he had spent a lifetime in politics being RUTHLESS! He was know for it when he was in the Senate and still was as VEEP and president.
Wanna talk about corrupt, evil, ruthless, and CRUDE? That was LBJ in spades! His language was dirtier than what runs in sewers and cesspools! He gave interviews to reports whilst deficating on the john, with his pants around his ankles!
Obama? Hell...he had Pelosi and others do the arm twisting, as any other Dem president would have. Obama was and still is an arrogant, egomanical, self aggrandizing blowhard with effluvia for brains.
I don't think that Obama twisted anyone's arms. He had Dems entirely on his side with both the House and the Senate for the first two years. Then he had a phone and a pen for executive orders for the next six. During that six the media was entirely on his side and the judiciary did not seem to challenge him. Johnson, on the other hand, was a master arm-twister.
Trump also has had to do everything he does under the cloud and threats of the phony Russia investigation.
"...“His chief promises were that he would build the wall, defund Planned Parenthood and repeal Obamacare, and he hasn’t done any of those things,” Carlson said, adding that those goals were probably lost causes. Trump, he said, doesn’t understand the system, and his own agencies don’t support him. “He knows very little about the legislative process, hasn’t learned anything, hasn’t surrounded himself with people that can get it done, hasn’t done all the things you need to do, so it’s mostly his fault that he hasn’t achieved those things..."
Tucker cherry picked Trump's goals because he hates Trump and chose the ones from the get-go that were going to be the most difficult to achieve. It is ignorant and biased at best, and malicious and stupid at worst. Tucker Carlson thinks that if Trump somehow finds a way to get people who know how to do "all the things you need to do" and becomes less outspoken and combative (nicer to the people who despise him, who turned the full force of government institutions to spy on him and his team and frame him in order to hamstring him and possibly remove him from power) then he is going to accomplish far more.
That is ignorance. Some might call that the language of the swamp.
Those days are long over. There is no "compromise" with the Left, because their view of "compromise" is to do what they want. We have seen how that goes. Our only way forward is to politically force things down their throat, and Trump is the person for just that because he doesn't give a damn if they don't like him. That makes Trump markedly different from every non-democrat who has run for office or held office since the mid-Eighties when the radical left began taking over the levers of power in the Democrat party.
As for the results of the mid-term election, that was standard fare and happens the majority of the time to the party holding the White House. To say that was a referendum on Trump is wrong, and possibly more in line with your last paragraph.
