Yeah. There's quite a bit of evidence that Trump does believe in many of the things he wants to do. As I said, it's not because he's a conservative. But I do think his heart is in it with the border issue. Also with trade. He's been preaching all that stuff for years before he decided to actually run.
And actually, I think the only logical argument against the wall IS the cost issue. I agree that the politicians who were once on record approving border barriers who now are using the cost issue, are probably just being political. They don't want Trump to have a victory.
But about the cost, it's expensive beyond the proof that it will be worth the money. It seems to come down exactly across political lines which side you're on there. Which makes it largely deterministic. I don't know if it would be worth the cost. I suspect it could be. There's a fair argument either way, but since the current opinions appear to be deterministic, I can't say I trust either.
Oh, please. If we're allowed to fail to allocate funding for anything that government wants to do for which there's no proof it will be worth the money, I can balance the budget in a year
And I'm waiting for the long list of modern examples where walls have not performed as advertised
