The very scary part is maybe Trump is stupid enough to actually push for the s**t that gushes from his empty brain.
What a disaster for America if he was elected. And for the rest of the world.
I think he is... or at least, he has a big enough ego for it! A recent article by NY Times highlights how he buried the USFL, blamed everyone else for it, and is now regarded as a "successful businessman" where in reality many of his business dealings were failures or less successful than ideal due to his egotistical bumbling.

Nowadays, he's more of a marketer of his own name than anything....and unfortunately for the US, doing quite well at it! Cruz is no better (potentially even scarier, in some respects) so the only reasonable hope for a moderate Republican is Rubio (Rubios fish taco's, MMMmmmmm..... sorry, back on topic

, a fairly young guy who could get out-dueled by Trump & Cruz in public debates. Sadly, a major deciding factor in the Presidential election is how people do in one-on-one debates, not how they're judged for leadership, building consensus, team building, foreign policy, domestic policy, economic policy, inspiring national strategy, building ties with allies.... You know,the shit that Presidents should be doing (I think) about 99% of the time. And Cruz is considered a fearsome debater while Trump seems adept at pulling at emotional strings for those desperate for change.
My personal hope/theory - Trump entered the race to further drum up his business and will pull out after destroying the hopes for any reasonable candidate, leaving the Republican party in shambles and allowing the Democratic nominee (Clinton or Sanders, I'm sorta rooting for Sanders but I think Clinton would do OK if the Republican party (Congress) wasn't so adamantly and illogically anti-Clinton, even more than they were anti-Obama) to walk away with the Presidency.
The other hope - the Electoral college (please don't ask me to explain it...) was originally put into place so a supposedly intelligent group of folks would ensure "Mickey Mouse" or some other jokester/write-in wasn't voted into the most powerful position in the country by the uneducated masses. As far as I know, they've always voted per the popular vote in their respective districts, but maybe they would actually do their job this time & prevent a global disaster if Trump were to be elected.
Trump & Cruz - just one of many reasons I moved to Canada :-D (I'll help build the wall to protect Canada, btw!)
