It's not that this isn't a good direction, but there is a reason why the GOP uses abortion, gay marriage, and immigration as scare tactics. I'd be amazed if the GOP can all of a sudden have candidates that can win primaries on a platform of immigration reform. The "Base" doesn't want that. Just ask Rick Perry. In the short run, libertarian light candidates won't get out of the primary (at least not in the near term) and in the long run if they do then that will open the door for Dem in-roads in the South through economic populism.
