Yeah because the alternative; Hillary, is too horrible to even consider.
Hmmm.. that's interesting because looking objectively at Hillary's record of statements and the positions that she has taken throughout her time in the public spotlight versus Trumps past statements and positions that he has taken throughout his time in the public spotlight, it would appear that Hillary is to the right of Trump on many issues.
Not that I would recommend anybody vote for either of these two miscreants, just that Hillary's past indicates she's more inline with conservatives on issues like foreign policy, national defense and even (as counter-intuitive as it sounds) government spending. Hillary is a liar, cheat and thief but she has been more consistent over the long term than Trump has on the positions she's taken.
At the end of the day it's pretty clear that Trump is nothing but a populist demagogue that will say whatever his target audience wants to hear and doesn't operate on any sort of philosophical principles and aren't conservatives all about principles? What are conservatives going to do if/when Trump gets elected and then proceeds to break each and every "promise" he made during the run up to the election? He's already started back tracking on the positions he took during the GOP primary elections and since he hasn't demonstrated any adherence to principle why would any conservative trust him on ANYTHING he promises?
