This Bundy dude isn't saying anything a clear majority of white moderate-to-conservative voters don't believe and articulate every day. If you don't understand that, you have probably not been exposed to very many white people.
The point is, if you think being associated with this guy is going to in any way harm the chances of Republican politicians who spoke up for him you'd be mistaken. Sure, they'll "publicly distance" themselves or whatever but the base remains fired up.
Just remember NOLA.com comments are pretty terrible but there sure are a lot of them.
