President Obama's campaign slogan is enduring a round of mockery, as Republican groups try to undercut the president's reelection bid rollout ahead of his first scheduled campaign rallies this weekend. 

The Obama campaign released a lengthy web video on Monday under the title, "Forward." Perhaps not as catchy as the "hope and change" mantra of 2008, the slogan was mocked on Wednesday by presumptive GOP nominee Mitt Romney. 

"Forward is his new slogan, and it's like, forward, what -- over the cliff?" Romney reportedly told donors. 

Making the obvious retort, conservative political action committee American Crossroads released a new video Thursday titled, "Backwards." 

"The only thing moving forward under Barack Obama -- our national debt, up $5 trillion," the narrator in the ad said. 

Rep. Michele Bachmann, R-Minn., even took a crack at it in her endorsement Thursday of Romney, calling the November election the "last chance we have to keep America from going 'forward' over the cliff, as Gov. Romney said."
