If Romney is going to hammer it, I would hope he would start soon. This is the defining moment of this election. If Obama/Dems?MSM succeed in portraying Romney the way they want on this issue, it is over.
The time for push back is now. Turn this issue to your advantage and run offense with it.
This is low hanging fruit. If Romney/Ryan/GOP can’t take advantage of this then there is no hope and there will be no change.
