Example one is the Romney campaign's push that it's Obama's economic policies that are the real "war on women."
The effort to point to an "Obama Rule" over and against the "Buffett Rule" looks the same to me.
This might be a good talking point at some level. It gives the campaign an affirmative argument on a big issue, which is always at least a bit better than having nothing to say at all. But fundamentally, this is Obama's turf. It's me-too. And you hope to keep up that way, not win.
