Romney says his business experience and taxes are off-limits

Huh? Romney's business experience is the central component of his entire campaign. But now Romney wants Obama to promise that he won't run any ads criticizing Romney's business experience?
Sure, so long as Romney agrees that Obama's presidential experience is off limits too.

Someone is seriously hurting.  More from Politico:

Talking about candidates' personal finances is hardly novel, nor is it irrelevant — how candidates make their money, however much or how little they've earned over the years, is not only fair game but a legitimate line of inquiry. The question of tax returns is also not new (to that end, Romney has said he would also release his 2011 taxes, but has yet to do so, with less than three months to go in the race).

What is surprising is hearing a candidate say, essentially, "stop hitting me." As the folks at First Read note, this would seem to be something of a concession that the negatives are bothering the candidate, whom a round of new national polls shows running at a deficit that exceeds the margin of error. Some of the attacks have indeed gone rather far over the line (the ad that yokes a man's loss of his job due to Bain Capital to his wife's death was at minimum factually off and at most suggests a pretty ugly thing about the candidate).

The Obama campaign put together a nice video about a month ago of Romney making all sorts of personal attacks. And now he's asking President Obama to pledge not to make personal attack? Romney has spent months suggesting that the President is a socialist, among other things. And who can forget Romney's staffer, who still hasn't been fired, who said that Obama doesn't understand America's Anglo-Saxon heritage, presumably because he's black, and black people don't get "America" - at least not in Romney-land.

Off limits?! Ah, ...  No!
