Lie Detector Test, Anyone?

Politics can be very confusing. One day, I listen to Herman Cain and think, "This guy would make a great president." The next day, a woman I never heard of comes out of nowhere and accuses him of making sexual advances to her, and I think, "Oh, my. Another Bill Clinton. We certainly don't want him for president."

Then, the next day, Mr. Cain comes out and denies ever sexually harassing anyone and even offers to take a lie detector test to prove it. In the meantime, several other women are lining up to make similar accusations against the man.

What is the average voter to do? Maybe the solution is to have them all take lie detector tests. Will it come to the place where truth serum is a requirement for running for office? Someone is lying. The question is, who?
