Wow. It's not that simple. Like an onion, I have layers.
The most important layer is character and integrity. Trump's obvious, albeit ignorant bigotry immediately disqualifies him from further consideration. Add in his fraudulent business practices and he's not simply 'questionable', but someone to be avoided at almost all costs. However, there have been many accusations of corruption and lying directed at Clinton. Upon careful scrutiny, I find partisan distortions and deceptions in every one. Clearly, Clinton is the best choice at this level.
The next layer is their history. What have they accomplished? How have they failed. Clinton edges Trump out here, but I'm not that impressed with either of them.
Finally, I look at their platforms. If I were to assign a single word to either campaign, his would be divisive and her's would be inclusive. It's no secret that I feel Trump has run the most negative campaign possible. His house of cards has been built on nothing but FUDDD: Fear, Uncertainty, Doubt, Distortion and Defamation. Clinton, on the other hand has been giving us positives all along. Has she gone negative? Sure. Trump is an easy target to get all negative on.
