I'm not so sure McCain being more moderate was his downfall, infact a hardliner would have done worse since the republican party must change to suit the voter or die. I think the main thing Paul has going for him that will sell, or I hope will sell next time is he puts the needs of this nation first and understands we can't rule the world by force or by buying them. he's a seperatist and in todays world that may not work too well, but what we've been doing sure isn't working at all.
