I only learned about Santorum being a Romney man in the last half hour.
It explains why so many of our romneybots have so fiercely jumped on his band wagon.
Using Santorum as their beard, they can attack Newt, and serve Romney at the same time.
I'd ridicule you for that, but I have to admit I just learned that myself.
Of course, in 2008 Herman Cain endorsed Mitt Romney, and I don't remember that being an issue for Herman Cain supporters, most of which are now Gingrich supporters.
Santorum endorsed Romney in February of 2008 -- exactly the same time Herman Cain endorsed Romney.
Maybe you attacked Cain supporters because he had endorsed Romney -- if so, you are consistant, although I haven't found any such reference.
