Probably third party;ultimately; Vitter is a hypocrite so I'm voting for his challenger in the Republican primary but then whoever wins will be a social con going against a liberal Democrat and both ideologies turn my stomach so the Libertarian Party may be my only option. My Congressman is a Republican who was a Democrat six years ago when he won so his record is a record of "bring as much government pork home as possible and ban th queers while spreadin mockracy " so that option is out, so again it's back to the LP on that one, it looks like anyway.
