Every vote is a moral compromise...as nobody agrees 100% with any candidate on every single issue. Which means that in every case, you are voting for someone with whom you disagree. So the question is a matter of degree, how much you disagree...meaning every vote is a compromise rather than an exercise in perfect moral rigidity. And yes, in such situations anyone with common sense makes a calculation when they are faced with two candidates for one position...particularly a position as critical as the presidency. Knowing that one of the two (Hillary) will cause irreversible damage to the Republic and cement a liberal agenda for the next two generations via liberal SCJ's....means voting for the GOP candidate is not a moral lapse, but actually a moral necessity.
Here's an example. All interest you have to pay is a necessary evil, so when you choose between a 4% mortgage vs a 6% one you have chosen the lesser of two evils. As any intelligent person would do. Of course, we'd all love 0% interest but that doesn't happen in the real world...we always have to choose that which is least negative for our finances. Call that "evil", but in reality is simply choosing the best available option.
So yes, it almost always makes sense to choose the lesser of two "evils"...particularly when one evil (Hillary) is vastly more harmful than the other. The garbage about "well, they're both still evil" is a cop out...when you have only two choices (in effect) and one is much, much worse than the other. You have the right to ride your moral high horse and allow the vastly worse evil to run rampant, or you can mitigate any potential harm by choosing what is clearly a more benign choice.
And let's be clear here, what we're talking about are degrees of disagreement with candidates rather than genuine evil. This is not a choice between two sins, its simply picking someone who you agree and or disagree to a greater/lesser extent than another candidate. Everything you assert beyond that is simply drama and weak justification for being childish and petty.
