That’s a pretty good assessment of what is going on. Well done. I don’t think Trump will be dumped tho. This is just getting started. Trump will be the guy who helps take us to the next level.
The bottom line is this: the GOP-E has time and again let Conservatives down. They say what we want to hear during the election cycles, then shove us aside afterwards. Our voices have been squelched.
I'd argue right-of-center more "mainstream" Republicans have also been shoved aside in favor of the left-leaning Republicans who are all in favor of big government (as long as it's THEIR big government) and more liberal social policies such as gay marriage, unfettered abortion and creeping fascism (Government and Business' in collusion together) while also cozying up to the Democrats and refusing to stop massive progressive leftist extremism, while brokering power sharing agreements with them.
Democrats have done the same to their Blue-Collar/Blue-Dog constituents who've also been shoved aside in favor of an extremist left-wing agenda in favor of everything from "gay rights/gay marriage", an EPA run amok, environmentalism as a religion and shipping manufacturing jobs overseas --- and that's just for starters.
The result: a huge pool of disaffected voters, pissed off at the party establishments and ready for radical action, if not radical change itself.
Donald Trump gives voice to all these disaffected / disenfranchised voters across the center/right of center of both political parties. I predicted MONTHS ago that Trump would attract the blue collar/blue dog democrats -- and he is, in increasing numbers. Trump may be the 'deliverer' of all these votes, I think it remains to be seen if he'll actually be the agent of change.
