It would do the Romney team well to think long and hard about why he can go to a group like the Value Voters Summit and tell them absolutely everything they want to hear, and avoid any serious discussion about what might make them uncomfortable about him, and still get wiped out in the on-site voting. His Mormon faith (unfairly) has something to do with it surely, but it probably has more to do with the sense that he lacks a core.
My sense is that Romney has a core on the points I care about and doesn't have a core on the points those at the Value Voters Summit care about. I hope his team pays some attention to this advice.
