Rule Four from Rules For Radicals...

Rule 4: Make opponents live up to their own book of rules. “You can kill them with this, for they can no more obey their own rules than the Christian church can live up to Christianity.”

So Romney claims that his work at Bain Capital created jobs. Obama takes the same set of circumstances and accurately demonstrates that at times Romney's firm caused jobs to be eliminated, an argument that enrages the working class. As long as Obama has Romney on the defensive on this issue, there's no room for discussion of the really important issues. It's a great tactic that seems to be working.

Don't get me wrong. Right now, Obama is using the "rules" better than Romney. But if the Romney campaign could use some of the Rules for Radicals themselves, they absolutely would. They've worked very well for a long time.
