?Trump is not motivated by conservative principle. Neither is Hillary Clinton. Without that motivation, we are merely one rationality away from tyranny. For my money that’s a working definition of evil.
And the difference is that if Trump gets into office his failures will be blamed on conservatives and will have hell to pay trying to  a conservative in the office again.

If you believe that we are capable of recovering from the damage that Obama has done, then we are certainly capable of recovering from anything that Hillary Clinton will impose on us. But we can’t recover it all without the conservative movement being strong and healthy. 

With Trump it will die and with it the country.
Addendum. In response to some feedback ask yourself a serious question. The GOP has successfully buckled every time Obama wanted something. Do you really think that they’re going to stand up Trump when he tilts left?
