Perot's problem was what Trump's CAN be: he got by for a while on generalities: "Larry, we gotta get under the hood and fix the economy." That will work for a while, but at some point, you have to have a FEW big-picture solutions. For Reagan, it was tax cuts and rolling back regulation. It was winning the Cold War through a military buildup. Trump's first answer to ISIS was "I'll find the right general." Down the line, that won't work at all.
Now, he has plenty of time to develop these---and he needs to stay FAR away from very detailed solutions like Cruz has proposed with his "replacing" Obamacare. (I spoke with Cruz about this: his HSA solution is a total loser because people a) don't save and b) don't see tax benefits if they ain't paying taxes to begin with).
My point is, most presidential elections are NOT won on specifics of policies, but on the inspiration generated by confidence and connecting with people. And Trump definitely has those two covered.
I agree with you on your earlier comment about Trump shaking things up. If he continues to punch back, hard, when the press goes into their smear mode, he will provide a tremendous benefit, so far as energizing the gutless.
I also agree with you, here, as to confidence.
As to Cruz on replacing Obamacare, I hope that he will persist. So far as Health Savings Accounts; I agree with you as to the strength of the issue as a talking point; but down the road, we have to find a way to get people--at least those with common sense--into saving. The economy is spinning towards eventual chaos, as the efforts to jerry rig us out of major downturns, become more and more extreme. That we are still trying to fully recover from a 2008 disaster, directly caused by insane over-leveraging in finance, is a warning flag that cannot be forever ignored.
