This new riff from President Obama is hilarious, hitting Mitt Romney over his “severely conservative” positions that he’s desperately trying to hide now.

The Obama campaign has focused more on Romney’s extreme right wing positions over his flip-flopping, but the Romnesia line nicely encapsulates both arguments.

Expect to hear much more of this argument for the rest of the campaign, highlighting Romney’s disingenuous attempts to hide hos own record.
