I was hard last week on Mitt Romney for his social policy changes combined with lackluster explanations of those changes while at the same time his campaign was attacking others on their social views, but let me say this about Mitt Romney, he deserves a lot of credit, all credit, for not letting up on Iran; in every interview and speech, he more than any other candidate hangs a light over the need for regime change in Iran, and not offering concessions to it.
