I'm helping support my local Libertarian candidate for office.

As for the presidential race, no way in hell do I want George Bush to win so I'll be voting for Kerry.

My personal opinion is that the Libertarian party needs to quit putting candidates up for president and start focusing on taking state offices. Once a govenor or state senator gets enough name recognition and power s/he can run for president.
