You say things like this whilst there are polls putting him below 35% in this thread (so outside the range you describe, and reputable source, too), and youâve only been able to dig up one which is even close to 45%%.
Further, youâre missing the point. The polls may have different numbers, but they donât have different vectors. Your poll and my poll have identical vectors. Sharply down. Your poll has him start at 48%, then go to 44%, the polls I can find have it slightly steeper at 40% or 39% going down to 35% or 34%, but itâs basically identical. Youâre claiming heâs âWINNINGâ, but heâs clearly losing. You can shriek âMARGIN OF ERRORâ all you like, but the vector is clear. This ainât going great for him.
And he just wimped out, and is attracting hate from his base now, so doesnât seem like his numbers are going to go up much. He might stablise the drop by reducing general dislike at the cost of increasing dislike from his base.
He doesnât really use it as a lever. Thatâs seeming his a conventional politician, which I agree with you that he isnât. His party tries to use it that way, but heâs just inconsistent. If you put DACA people in front of him, or have someone talk positively to him about it, heâs all for it - to the point where early in the presidency he nearly gave it away for free and over the screaming objections of the Republicans. It took some serious arguing with him to stop him. At other times heâs just been wildly against it. Heâs completely inconsistent and offers it solely because someone told him it was a good idea (and on some level he likes the idea - heâs a grandfatherly racist bigot, rather than the ideological lunatic racist some of his base wants him to be).
Further, you still donât seem to get that itâs a shit deal.
You think itâs a good deal because you are 150% certain Trump will get re-elected. Most people, including analysts in roles like your apparent one, do not believe that. Itâs obviously possible, but all 3 years does is get you to the middle of the next Presidency and then he can just refuse to go any further, or even potentially tear up agreements.
Also, and this is super-cynical, but it helps Trump in a way thatâs inconvenient for the Democrats, if he gives ground here. Whilst Trump is holding DACA and so on hostage, he offends the Hispanic population of the US, and other minority ethnicities. He keeps causing minor offence over and over by using it. The Democrats are not damaged by not agreeing, because their base doesnât see that as necessary. Yet if they did agree, whilst it would boost them a little with Hispanic voters, it would boost Trump more, and heâd roll around in it, luxuriate in it, never stop mentioning his âkindnessâ, which actually plays okay with his base (because theyâre mostly in two minds, the ones who arenât lunatic racists, merely bigots), not great but okay, and he might pick up Hispanic voters who are socially conservative but vote Democrat because in the last thirty years, itâs the âway less racistâ party.
Yeah, this has been an idea/concern for decades, but I donât see the simple resourcing and technology issues working out in the end. Itâs too easy for it to start failing, and once it does, itâs a chain-reaction. It also has the potential to fail from the inside out, because itâs obviously evil on a basic level that is abhorrent to literally all human religion, major philosophies and so on (barring Rand but sheâs a cod-philosopher). But the real issue is that it rejects the stabilizing factors that keep human societies upright.
Obviously it would cause horror in the short term, but in the long-run? It would collapse in on itself.
Itâs also a not-very-good movie called Elysium
