@Debra Law,
My personal rules for voting are:
- I will definitely vote. Not voting out of disgust is not a reasonable option.
- If there is a candidate running that I am truly passionate about I will likely vote for them even if they have no chance to win.
- Otherwise, I will vote for a candidate that has some chance to win.
I can see someone saying I am so passionate about Sanders I will vote for him anyway, but if he is not running, he is not going to get my write-in vote. I'm not going to vote for a third party candidate that I know nothing about other than policy papers and is likely going to get less than one percent of the vote. I considered Perot when he ran. I would consider Bloomberg if he runs as an independent. That said, if it comes down to Clinton vs Trump or Rubio, I'm going to vote for Clinton. I don't like all of her positions or all of her votes, but from rule one, I will definitely vote and voting a write in or third party would essentially be voting a half vote for Clinton and a half vote for Trump and Trump is not getting my half vote.
