Bobby Jindal proposed something like that
in Louisiana. It was a disaster. He eventually pulled the plug after his own approval ratings sank into the basement.
Funny thing happened to me yesterday. One of my most conservative clients was at my office doing year-end tax planning. He actually brought the issue up about the elimination of the income tax. To my surprise he was completely against the idea, he said that was too much and affected the poor unfairly.
Honestly, I couldn't believe that he said that. If the Rs are losing their base, white males who make $150,000+ on this issue I don't think it will fly.
