I think one good example that is very current and stands out IMO--Ethanol. It is a joke at this point in time. When the mandate was passed, we were in a completely different situation with respect to oil imports. So the10 % mandate was passed. All of the downsides of ethanol were known but it was I think considered the lesser of two evils. Well a lot has changed- like it or not, fracking, tar sands production, recovery from old "played out" wells etc has changed things. To say nothing of the fact that the diversion of corn from a food stock to a petroleum stock has driven the cost of food up. In any case, they are in Iowa, "corn/ethanol" capital and what does Trump do? Sticks his finger in the air, tests the wind, and he is all for ethanol. Cruz to his credit, takes the very unpopular position and stands his ground that he is against it- and wins! Now some would say-"well he is from Texas-what do you expect?". I guess I would say, the true politician would at the very least, take a very low profile on the subject- much like Rubio who said..."i'm in favor of a phaseout by 2022. Bottom line, if you look at Trump and say..well he has done his job and raised some very real issues but his temperment and character is lacking, who is left? More importantly, who has run anything? built anything? hired? fired? met a payroll? had to worry about profitability as a means of survival? had to deal with a real crisis? Is prepared to pull the trigger? Always maintained the high moral ground? And handled all those things well. Answer those questions and that IMO is our candidate. One gifted public speaker in our lifetime is enough!
