Just as liberals don't generally try to make elections about smearing their opponent, a la John Kerry and Al Gore, they generally don't tell baldfaced lies. I said GENERALLY, I'm sure exceptions can be found.
GENERALLY the Republicans are panderers and liars who have cobbled together a coalition of religious freaks, bigots and deeply stupid people who think abortion is more important than the budget. They love the gutter vicious, name-calling type of politics that the Repubs specialize in, while Democrats keep thinking that if they stay above it the people won't be fooled. That's their mistake. Obviously, people are very easily fooled.
