I think Romney will stick with what worked the during the first debate and what Obama lacks -a plan to get the US thriving again.
Pounding on your opponent only goes so far, people need to hear about what you are going to do.
Obama had made Romney into such a monster that all Romney had to do the last debate is to prove he didn't belch fire or that his head didn't spin around periodically.
The vagina monologues has hit a sour note also. The DNC telling women to vote with their lady parts brought it all to an ugly head. I rather vote with my lady smarts.
They've gone from "vote like your lady parts depend upon it" to "Hold on to your lady parts or else"
"Stuff's gettin better"
