"It is a liberal canard to say I am personally pro-life, but government should stay out of that decision."

"If that is your view, you are not pro-life, you are pro-having your cake and eating it too."

Said Rick Perry at last night's GOP candidate forum in Iowa. It's a well-crafted line, intended — I presume — to trip up Herman Cain, who just a few days ago delivered up precisely that "canard." He's walking (waddling?) back from the canard, but — as Rick Perry also said last night — "Being pro-life is not a matter of campaign convenience; it is a core conviction."
