Donald Trump - an ignorant, mean-spirited, xenophobic, and self-serving racist who's willing to tell any lie he can conjure up to promote his own interest. That makes him the quintessential Republican, and that's exactly why he's leading the Republican polls.
So the Trump phenomenon says it all. While the GOP establishment claims to be distancing themselves from him - and they are - it's not because they disagree with what he's saying, it's because he's either too dumb, or too self-serving, to realize he's not suppose to be saying it out loud. The Republican establishment has been saying the exact same things for years, but in code and with a wink. So if America is perceptive, this Trump episode should bring down the Republican Party for decades, or at least get them out the way long enough for the country to get back on it's feet, because while they're constantly giving lip-service to wanting to help the average American, an unequivocal historic record clearly demonstrates that has never been the case, and not only that, it has never even been a part of the GOP's agenda.
