Here is a good article by syndicated columnist Victor Davis Hanson, “GOP running out of anti-Romneys.” The opening paragraph sums everything up nicely:
“Nominating Mitt Romney is sort of like taking grandma’s castor oil. Republicans are dreading the thought of downing their unpleasant-tasting medicine but worry that sooner or later they will have to.”
Unfortunately, I think he’s right. From a RKBA standpoint, the very slight edge Romney has over Obama on the issue is that he realizes that he needs to at least appear pro-gun in order to win, while Obama seems to be going for not looking openly hostile to 2A rights. That gives our side some leverage over Romney.
