It honestly seems that Ron Paul chose the wrong election to go into. I mean, the majority of the republican candidates are extremely right wing, while this would usually be to the advantage of a (comparatively speaking) moderate, the extremists are getting the sorts of people out and voting who would have thought that George Bush was too liberal, so there is an entirely new voting group in the primaries. This means that Paul is stuck between a rock and a hard place, as it would be impossible to win votes from this new extreme right voter group without alienating the moderate republican voters. While this wouldn't usually be an issue, as most politicians go for the biggest voter group (though it is harder these days, as you have to go pretty much for the largest group nationally, rather than locally as it is impossible to keep details of your campaigning in each region IN said region, which is how the racist vote was won in the past, by making sure that your more moderate areas of campaigning don't see what you did there) from the start, Ron Paul has already shown that he is trying to win both moderates and conservative republicans, and the ideological gap between the two has gotten too big in recent years for that to be a viable strategy (at least in the take part of your policies from the moderates, and the rest from the conservatives rather than a deeply researched compromise position).
TL;DR the republican voter base, while widely spread overall, is also tightly grouped in a few areas on the ideological scale, making a compromise political position difficult, especially when your opponents have the ability to get the whole of one section to vote for them.
