I am not big into country either, but have my own list of favorite conservative musicians:
Sammy Hagar
Ted Nugent
Kid Rock (not a fave, but I do have a new respect for him since finding out he's pro-Bush)
Metallica (James Hetfield is a conservative but not particularly politically active--definitely pro-gun though)
Poison (CC DeVille is a Pubbie)
I would love it if they had all those bands! Yeah I know I am just dreaming.
Dont forget Lynard Skynard and Jessica Simpson.
