A web ad Tuesday from Rick Santorum’s presidential campaign mocks an ad from now official presidential candidate Jon Huntsman and attacks him for not signing a pro-life pledge from the group the Susan B. Anthony List.

Huntsman’s original ad, one of several released in the run-up to his entry into the race, shows him riding a dirt bike and teases the announcement of his presidential plans as coming “in 4 days.” Santorum’s ad shows a dirt bike rider wiping out and says Huntsman “Hasn’t signed the anti-abortion pledge. Just like Mitt Romney…”

Huntsman and Mitt Romney, have been taking heat from other Republicans in the 2012 field over the pledge, from the pro-life Susan B. Anthony List, which supports candidates for Congress. Romney had written an op-ed explaining that he thinks the Susan B. Anthony List’s pledge to defund “contractors and recipients of federal funds with affiliates that perform or fund abortions” goes too far.

Here’s Huntsman’s original ad:

And here’s Santorum’s version:

Huntsman’s campaign responded to the ad in an e-mail to CNN:

People who rely on pledges usually don’t have a record. Fortunately Governor Huntsman, a life-long, no flip flops pro-lifer, has actually signed anti-abortion legislation into law - that’s a signature that makes a difference. Not only that, Jon Huntsman has lived it. He and Mary Kaye adopted two children, Gracei Mei who had been abandoned in a Chinese market and Asha from an orphanage in India.
