I am a bit curious. What is it that Trump will do as President that scares you?
Honest question.
Trump doesn’t scare me. He disgusts me. He’s a lifelong liberal sleaze and a liar. He changes his positions like he changes his ties.
An awesome and important question, and one that I hope you'll allow others to answer as well...
For me, I'm confident that he will be great on immigration and the economy... although the concern still exists that he may not follow Constitutional principles in doing so, and instead opting for the Obama approach so as to "get things done". Trump admires efficiency far more than he admires following the rules, in my mind anyway. After those, there is nothing that we can be sure that he "will do as President", which is also troubling. The religious freedom issues are still in play, as are ObamaCare, gun rights, etc. Then there is the troubling precedent of electing the wealthy, or celebrities, and both groups tend to be mostly clueless idiots (as is the majority of the electorate). Trump has always been about Trump, and I believe that his motivation in office will be about proving to the globe that he is the best businessman ever... again, not the worst thing in the world, but also could be problematic as egomaniacs like Obama are something we need to get away from, not double-down on.
Substantive enough?
