The Obama campaign continues its sandblasting of Mitt Romney’s jobs record as Massachusetts governor, running this ad in CO, FL, IA, NC, NH, NH, NV, OH, PA, and VA (via MSNBC’s First Read).

First Read notes that Romney has taken a new approach to defending its record: sort of ignoring it.

The Romney camp responds with this statement: “Having abandoned ‘Hope and Change,’ the Obama campaign only ‘Hopes To Change The Subject’ from an abysmal jobs report. We’re happy to compare the 4.7 percent unemployment rate Mitt Romney achieved in Massachusetts to President Obama’s weak record any day.” By the way, it was interesting to see Team Romney unveil a new way to slice up the jobs data for Romney’s tenure in Massachusetts. Our question: Why did you wait until now? The 47^th in job creation was a staple for the entire primary campaign and yet, no pushback like we saw this weekend. As the Boston Globe writes, the Romney camp has never disputed the accuracy of the 47^th charge.

Feel free to read the Globe story, but be advised: It will make your head hurt.
