This had nothing to do with RP. It had everything to do with Fred Thompson.
The GOP establishment in LA had picked the Thompson slate as the one they would all run on. Had he not dropped out, the finish in the caususes would have been Thompson-McCain-Paul instead of PLPF-McCain-Paul (pending provisional ballots, of course).
When it became obvious a few weeks back that Thompson might not make it to LA, the establishment came up with a fallback plan, the PLPF slate, because they figured people wouldn't want to vote for a guy who had dropped out.
Doing this also enabled them to reach out to a handful of other campaigns' delegates before the caucuses -- heck, they even included a token RP person according to one thread on this forum. That isn't cheating, it's just standard cooalition politics, the kind of stuff that goes on at every level of gov't every day.
This wasn't about Paul, this was just the LA GOP making sure no one took away "their" seat at the table.
