In this day and age with technology in the palm of your hand to access the internet at all times of the day, it is your civic duty to research the candidates to be better informed in your decision making. There is no reason to follow blindly with what the news media show you on television with the slant that is added to make the top candidates look better; or worse depending on the network, as the sole means to vote for them. Basing your vote based on your dislike towards one of the top candidates as the reason to support the other candidate is not the best way to go about this either.
Instead of choosing one of either the Republican or Democratic candidate because of those two parties, one of them is most likely to win, take a look at the other candidates that are running to see which one of those meet your Presidential criteria.
You have a choice.
