Romney is walking this back now, according to Allahpundit over at hotair.com.
Seems he thought the reporter was asking about the Ohio bill, whatever that is, and the reporter threw in the Rubio name with Blunt which is incorrect, he explains.
Romney was ill informed when he got the question and confused it with Rubio, who is offering his own bill, separate from Blunt.
He is only walking this back after it hit the fan. A candidate had better know what this issue is about. From the video, I got the impression Milt knew what the question was and gave us a moment of RINO candor.
