I don't expect my state to be close, though it was pretty tight in 2000 (some may remember the five weeks or so of recounts).
But it doesn't matter. I've never voted "for" POTUS, only against the Dems by holding my nose and voting for whomever won the R primaries. McCain was tough, told myself that was the last. Then I went and voted for Romney, but that was it.
Now I vote for the candidate that best meets my values and concerns, if there is one that is good enough. It's not about Trump. It's not about HRC. It's not about SCOTUS. It's about supporting Conservatives who respect the United States Constitution. After this round, if the GOP wants MY vote, they can nominate a Conservative.
