Walker does present his views effectively, for example this Scott walker interview.
You can tell he has some people on the GOPe side worried, considering that fake story about Walker and gun control that was a thread on FR a couple of weeks back.
But he does not bring an automatic 17% of the vote as some believe Carson can do with the black vote! The mathematicians among us say that 17% guarantees a victory for Carson. If that’s true, then that is persuasive if not determinative!
