Honestly I am scared of a Hillary presidency. However, I am more scared that we have already lost our conscience. I believe that the rejection of our conscience is a greater threat than anyone who might be elected. Character does matter. Integrity does matter. Our vote does matter.
Our founding fathers made our vote highly symbolic in a representative government. This symbol being our vote equals our conscience, our character, our integrity. We should seek out honest men of sound character who will represent our own character and integrity as well as the principles that we feel are best in governing under the Constitution.
How have we lost our conscience? We proclaim the virtue of competition in all things but voting. When it comes to elections 2 parties is all that count. If you vote outside that framework you are voting for the evilest of the candidates. Third parties have now taken on the mantle of the vilest of parties. Fear is a powerful motivator, it blocks the effects of conscience, it creates irrational thoughts, and it justifies uncharacteristic treatment of others. Fear causes us to act against our better judgment (conscience). This is how we lose our conscience, we fear the outcome more than we fear the solution.
I call this the pheasant syndrome. In the classic Disney movie Bambi, hunters enter the meadow and a mother pheasant begins to panic. In her panic the logical thing to do is flee from danger as fast as possible, so she takes flight and is shot dead. She would have been better to have stayed calm and not panicked. The real solution was to stay close to the ground. I have walked on top of a pheasant that understood this principle and it got away because I was unprepared to deal with a pheasant between my feet. He flew, but he did not panic, he stayed low and disappeared as quickly as possible.
Voting your conscience is not about voting for another candidate, or against another candidate. It simply means you are voting for the person you feel has the best character and will represent you, your principles, and your values best. Those who would attempt to make you feel otherwise simply are more scared of the outcome than they are of the real solution.
