One votes, presumably, to further their personal political beliefs.
Also, some vote to make a "statement", unfortunately, the statement is lost in the background noise.
I have seen some say they will vote for the nominee, sane choice.
I have seen some say they will abstain. Whatever, thanks for playing, pick up a door prize on the way out.
I have seen some will vote for Hillary, because the end is coming, and the quicker, the better, so that we can then start the long road to recovery.
I have no printable comment for them.
I hope, when the time comes, all the republicans all over America have an epidemic of sanity.....
