Common Sense: Say anything
I suppose one could write a column about Donald Trump every day. His constant stream of over-the-top statements certainly feeds into his strategy of keeping the focus on him as a personality without concerning oneself with the wisdom or for that matter legality of his proposals as serious public policy initiatives. If a candidate is willing to say anything without concern for consequences or accuracy, it is likely that he or she will create and maximize a super hardened base.
Teflon Trump is impermeable with that base. But just like a hard shell can keep things in, it can also keep things permanently out. The question in an election cycle becomes for Trump “has he hardened his base to a point and in such a manner that he has essentially created the impossibility for him to win a general election and maybe even a nomination?”
Polling and for that matter common sense indicates that on a national level, when all likely voters regardless of affiliation are surveyed, many of his proposals are individually and significantly unpopular. And taken as a whole, it has translated into Trump having an unusually high unfavorable rating and the worst head-to-head against Hillary Clinton of the major candidates. Marco Rubio runs the strongest in most surveys.
