The general theme of this thread is spot on. The notion that "it doesn't matter" in the primaries is ridiculous. If Ron wins the GOP primaries, it will be because a huge swathe of previously independent voters (or non-voters) have registered Republican solely to vote for him. It's the Islamophobic, homophobic, aging "don't touch my SS", neo-cons that are the real group to write off.
Most of RPs fans know about his positions on abortion: that a) it doesn't matter what the government says, because you can't stop a girl from drinking tea the day after forgetting to use a condom, b) it is not for the federal gov't to decide - leave it to the states, and c) nobody should be forced to pay for clinics - they should be funded privately if the states choose to allow it. But these stances definitely DO need to be clarified (again and again), because so many people are under the impression that its one or the other. They probably don't understand his constitutional starting point.
If it is made clear by Ron himself that he will never advocate: a) unilaterally banning abortion federally, and b) using the executive branch to force religion on school curricula, I'm pretty sure that would be enough to placate voters that would otherwise be terrified of him. If the "scary" part is taken away, I'm sure many (like myself) could be convinced to support him based on other issues. But ya gotta remove the fear. People vote based on their emotions, and these emotional, divisive issues evoke fear.
