The perfect cartoon for the midterm season

[neophyte]

This is exactly the type of TV ad run by the dem and repub candidates for governor of South Carolina, at least in the Charleston area market. No ads about themselves, just ads that bash their opponent. Why is it that they expect me to vote AGAINST someone rather than FOR someone? Are they tacitly agreeing that I should vote for the "lesser of two evils"? Doesn't say much for their intellect, nor anything about the issues facing our state.
