So we are unhappy with most democrats, because no matter what they have said or done, they will rally around and defend their candidate. Yet when there are actually members of the republicans that say "I cannot, in good conscience, vote for this candidate", everyone screams bloody murder?
Got it.
We also have people getting in a lather about third party and write-in votes being, "a vote for Hillary". The electorate is pretty divided, and the establishment on the other side is getting in a lather about third party and write-in votes being, "a vote for Trump".
So in the end, those on either side worried about people voting their conscience should consider it a wash. The bonus (for me) would be to see the combined third party and write-in percentage be higher than the percentage for either Clinton or Trump.
One of them is going to get it, but if everyone actually voted their conscience, especially this time around with the low approval for both candidates, the high number of votes for all the people not them would absolutely send a strong message.
