The Dems are looking for someone perceived as conservative to give their ultra-liberal presidential nominee a boost. Unfortunately for them, that means they’ve got few to chose from. In Webb’s case, they can have one of the most conservative Dems in the Congress, but with it comes the image of meanness.
Republicans should be aware that Virginia was a conservative state. If you think Virginia will be a cake walk for Republicans again, you might want to see just how sad the state has become. It seems the state is being invaded by loons. Northern Virginia is now a left wing haven. I believe some little towns are competing with welfare being the gift. Some towns are food stamp friendly and others are rent free voucher friendly.
You may be confusing meanness and mental instability.
