Because cynicism is for the weak.
Yeah well, Rand screwed his campaign up and dropped out early on. Love or hate him, Trump sold Trump to America. He knew what they wanted and he gave it to them by the triaxle-load. Had Rand been on the same ball, he might have survived into the election.
Once again we see the difference in effect between the normative thinker and the positive. All the high-minded principles buy you nothing in a world that doesn't speak that language. Trump had his hand on the simple-minded meaner's pulse. Rand did not. Rand spoke to a vanishingly small minority of better-clued and braver Americans and the rest of the nation turned their backs to him. That is the reality. Trump spoke to the average drooler, got him stiff in the shorts, and left him with the promise of happy fun time if the votes come in. It was masterful and as we all see, it worked.
Nowhere did I imply we should be. Elsewhere I wrote that we should all be jumping on this bandwagon in the effort to steer it where we know it needs to go. It's the ONLY vehicle available at the moment. You can sit with your thumb in your ass for 4 more years in wait for the Messiah to arrive for 2020, or you get your ass moving. The worst that happens is that "we" have no palpable effect. You are no worse off.
We should see it shortly. But your order of operations bespeaks fear and weakness - no slight intended. Why be that way? Why be afraid to be fooled just one more time? You should know soon enough what he's about. You can retreat into anger and disappointment then, if it suits you. Until then, why not take a chance, however remote, that he may leave the nation better than it was in four years. I've read that he will sign legislation for national concealed carry. I would call that am improvement.
Time will tell.
