Not sure why this is a story, as there is no incentive to vote Republican. They have demonstrated no leadership in fiscal restraint and responsibility; no leadership in smaller government; no leadership in moving beyond the inbred politics of the status quo. In short, Republicans have not distinguished themselves from Democrats, so why not just vote Democrat?
The only thing close to a Republican running may be former Republican Bob Barr, to make his run for office as a Libertarian.
Really, why Republican?
