Come on now ... they wouldn’t let Al Gore in the R party.
Okay, I’ll play. If his opponent (a democrat) was more conservative (and sane) I suppose I’d break my rule and vote D. But, remember this was just hypothetical.
Why not? They let Arnold Shriver SchwarzenKennedy do it and he's pretty much implementing Hillary Care and Gore's enviro-wacko Global Warming regulation while destroying the GOP at the same time.
Rudy would be more of the same, except on a national level.
