Hillary's campaign released a new 'comparative' ad this morning:
It's unclear whether there will be enough money behind it to 'burn it' in to the minds of Democratic voters, but it will undoubtedly get picked up in the blogosphere and analyzed.
The ad is apparently being played only in Texas, which may be a sign of the Clintons' desperation there; she trails by 2 points on a blended average basis (as opposed to Ohio, where she is still clinging to a small 5-point lead, according to RCP.)
Update: Playing the ad without the sound reminds one of an ADT ad.
Of course, maybe that was the point.
