If you think that the remaining percentage of voters NOT included in the '47%' really agree with Mitt's philosophy then you're deluding yourself.
The only ones who really support this 47% exclusion are at the base of the Republican party. Most Independents reject this idea and it will cost him voters.
Personally, I hope he sticks by it. Double, triple, quadruple down on it; run with it in the debates.
Excuses are tools of the incompetent used to build monuments of nothingness. Those who use them seldom amount to anything.
