I'm talking in the last 20 or so years. They love pointing to some 'Republican' on some local city council in Podunk, Kentucky getting caught stealing from a 7/11 and other trivial matters to justify their argument that all Republicans are 'evil'.
I know it is a flawed argument at best, but most of these people haven't had any formal training in logic or reasoning skills.
I can't hold that against them.
Well then, as the earlier posted commented: don't waste your time arguing with a hog.
Just ask them, If dems are not corrupt, why are they SO against picture id's at the voting booths?
