But you haven't addressed my main point, which is that no election ever puts us in the position of voting for good vs evil. Because it's always two (or more) flawed humans each with their own mixture of good and evil. If the argument is that we can never vote for someone who takes/have taken/likely in the future to take even one evil position, then we should abandon the entire concept of having elections.
Election are almost always about picking the least worst option, it's just in 2016 the least bad option is worse than it's ever been.
Let me put it this way, sometimes the choice appears to be between the perfect and the good. Unfortunately, we're not choosing between George Washington and Thomas Jefferson, but between Hillary and Donald, or, as I have put it, a choice for the future, when the ashes of the GOP are cooling, an opponent to the Marxists with the US Constitution for a platform.
In this case, the 'lesser evil' is problematical.
First, there is the question of stance on the issues.
We know Hillary is a corrupt Socialist who will treat out military with contempt and our nation as a source of revenue, who will enact a Socialist agenda for fun and profit.
We have been told by a man who lied mercilessly about his opponents through the primary campaign that he would do things he has no power to do if elected, and he has walked back those seminal positions. He has harnessed the anger and frustration of a significant voting bloc, but anger and frustration don't work together to craft wise policy at home or abroad. Many of the positions which allowed him to harness that anger he has reneged on, and the votes aren't even in. What he does bring to the table are liberal stances on a wide variety of seminal conservative issues, stances which are as socialist or more so than those of his opponent. This isn't anywhere close to Conservative belief, and by endorsing such, the GOP loses its claim to conservatism, by abandoning those core beliefs.
I am first and foremost a Constitutional Conservative, if I have to pick a label, and while the GOP has treated my ilk shabbily in the past, this will leave those of us who are fighting to keep the concept of a constitutional Republic alive with no place at the table. All the more reason to not support the GOP, which will, in essence with the embrace of Liberal positions on issues, effectively render its party platform moot. Why contribute to that when there is another party which embraces all I believe in and the Constitution? Better to build that party into a political force rather than spend any more time and treasure trying to get the GOP to even slow it's shift to the Left. That helm has been unresponsive since Reagan, and the vessel is headed for the rocks.
I see voting for Trump as accelerating that process, not slowing it, and while Hillary is a predictable outcome, I wouldn't vote for her either.
There are those who claim Trump will do this or that which will "Make America Great Again", but he considers Government to be the dominating factor in that. America is Great. America would be greater if the government would get the hell out of the way domestically, and do what it is supposed to do--and no more. (Provide for the common defense (including securing the borders), coin money, settle disputes between the sovereign states, provide standardized weights and measures for trade, and keep the post roads open).
Then, ultimately, we are left also with a question of credibility. For one so given to incontinent prevarication to have any credibility with the electorate is simply amazing. We have been lied to before. If anything that is a great source of the anger Mr. Trump has harnessed, in that the Congress elected to repeal Obamacare or stop its implementation has caved in every respect to the Obama administration, giving it all it has wanted and more. While there have been a few stalwart Conservatives in the Congress, the majority succumbed to 'Beltway Fever', some even before arriving in D.C.
The sad part is that Mr. Trump has already walked back the conservative positions he espoused to harness that anger, and is currently in competition with his opponent, promising to deliver even more free sh*t than she will because he is not one to be outdone. That to me is evil competing to see who is the more perfect evil, not the lesser of anything.
Outside of that snake pit, though, there are options. There are 70 plus other parties in the United States, some quite serious, some better known, some perhaps political satire. Of those parties one has embraced the Constitution of the United States as its Party platform, and has embraced the original intent of the Founders and that wisdom as the model for the Government which should go forward. That would return power to the States and the People, reduce the size and scope of the Federal Government (and expense), and roll back the clock on globalist entanglements that threaten our sovereignty as a nation, especially the ceding of dominion over our lands and policies to the UN. What's not to like?
