I think it is far better to vote for someone, than it is to vote against someone.   Vote for the person you most believe in.    There is no perfect candidate....ever. Get over that fact.   

I have voted for both Democrat and Republican presidents.   There have been other times I have voted, but did not vote for a president because I did not like either candidate.   (I think it is important to vote for all the other issues beside president)

Don't just vote against something.   I remember a line I heard 30 years ago.   "It's not the lesser of two evils, it's the evil of two lessers"

As my friend Utah Phillips says "a man put a gun to my head and asked if I am voting republican or democrat. I said shoot me"   Fill in the two candidates names and that joke almost always works... in almost every election...in almost every country.
