Donald Trump seems to be determined to upset everyone, based upon his latest debate charges and attacks. His value I think is to PUSH the GOP, and Candidates to address issues of concern to regular Americans, and not PUSH the issues valued by a few large donors, such donors having their own interests, whether they donate to Democrats or Republicans.
Donald's "Code Pink" style attacks on former Presidents Bush 41, and especially Bush 43, as part of Trumps attempt to shut up, shut down !Jeb!, will ill serve Trump and the GOP, should he become the Nominee. We shall see how it all goes, including the current Primary races, and whether "The Donald" can bring himself to address actual issues, rather than such biting personal attacks.
Marco Rubio, seeking to out-trump Trump, is becoming entangled in his claims on the debate stage as well, in an attempt to disparage Ted Cruz, winding up calling Cruz names, when it was Cruz whose statements were dead accurate. Marco acts like Bill Clinton, being 'too slick by half' at times, and is good at it, until his sentence is parsed later. Whether this will affect his desire to BS some of the people all of the time, and continue to gain traction as the Primary elections proceed forward is to be determined.
Saying one thing in English, and a different thing in Spanish, then trying to ride out the news cycle disputing the transcript, versus his press handouts in English, is dubious at best. Lies matter, and disparaging a fellow Republican Candidate matters, and one can only hope the Voters recognize when they are being fooled.
Primary elections are for accumulating delegates. The comparison of candidates in pressure situations is of great value, and glib speakers gain an initial advantage. The actions of an elected official who is a candidate have a record, and when the Press takes the opportunity to research and detail a candidates record versus statements, the greater good is served.
Unfortunately, such comparisons are only well done by 'new media', as MSM (mainstream media) has little interest in other then pushing the candidates they support, and sneering about all others, so no real comparison is readily available, except to those who look for it.
