There is nothing more dangerous than an uninformed voter.
Choose wisely. Take some time to research the candidates.
Don't listen to what a candidate says or what the media says about them; research their accomplishments. Use common sense. Look at their associations and their actions to help you judge their character.
Ask yourself: Is this person capable of leading during the most challenging times in recent history? We spend more time researching a purchase than we do on choosing our elected officials. Is this wise?
