I can bet that Huckabee supporters are claiming that Mitt Romney is attacking Huckabee - and trying to make claims that there is an equivalence after Mitt went after Huckster.
Mitt Romney went after Huckabee's Kos-esque criticism of President Bush. He also compared his record on immigration. Neither compare to Huckabee's playing of the religion card.
To claim they do defies logic.
Still, some will try to defend it.
