They don't really exist as they used to, no. And I don't think it's accurate to say he got everything he wanted.
We aren't governed in a dictatorship. Compromises have to me made, that is the essence of democracy. We the People are supposed to be represented. This bipartisan agreement was a total bend over by the Dems. The fact you don't see it that way is beyond me. He got everything he wanted AND got approval for American taxpayers to pay for it. Not a peso in sight.
If Trump ever merely sought 1.6m for the wall (I know that's the DHS request), and then came back later and said "oh that's not enough I need a firm commitment for the remaining billions," then you're correct. But I doubt that's the case. I suspect Trump's position has been he wants a commitment on the wall/border security as part of any resolution of DACA, and just a fraction of the wall would be a non-starter.
The $1.6 billion for the stupid wall was year one of the DHS's budget for the idiotic wall. He does not deserve a blank check of American taxpayers money over 10 years until the costs and other factors are analyzed. Did I mention that he is asking for $18 million of American taxpayers money? He is going FAR BEYOND his campaign promise and yet it's still not enough.
If you see border security/wall as a necessary accompaniment to any pathway to citizenship for a couple million people, why would you take a fraction of what you think you need to accomplish that objective? Democrats would get essentially everything they want now, while 90% of what you want is deferred and can be subsequently obstructed. If you're a Trump voter, wouldn't you be pissed if the "master negotiator" did that deal?
He got everything he wanted and then some in that bipartisan agreement. Both parties sucked it up and played the game. He threw his toys out of the pram because Miller told him that his base would flip out over the DACA part. Simple as that. If you could show me his exact proposal he presented to the Gang of Six regarding his repayment of the wall funds he's requesting then I'm all ears. Otherwise keep blindly supporting this wannabe dictator.
So damn frustrating arguing with brainwashed people. He could have had a rally in Bumfudge, Alabama and easily have spun his bigly deal making skills.
