A couple of things come to mind.
I tend to vote for who I think is the best candidate to handle the circumstances we as a nation face at the given time.
Personally I wish both parties would stop telling us if they are "pro-choice, "pro-life, in favor of marriage equality or not....etc"
Those are (personal) decisions that should be left up to the individual.
The liberals don't want the government telling them what they can or can't do and the conservatives don't want the government telling them what they can or can't do.
They just disagree on the type of gov. intervention they do want!
The main things I'm looking for are candidates who are dedicated to building a strong economy and defending the nation from terrorists.
Everything else pales in comparison in my opinion.
