The top two issues on voters minds, according to all polls, are the economy and ObamaCare.
The moderators of all the debates are liberals - every one.
The last thing liberals want is for the debates to focus on the economy or ObamaCare.
My prediction - there will be very little focus on the economy and ObamaCare in the debates. The liberal moderators will avoid those issues as much as they can. And when (if) they do pose any questions on those two issues, they will focus on Romney's response. I seriously doubt they will hardball Obama on those issues, because those issues are losers for liberals.
