With all due respect, I suspect using the "Freeper" connotation is going to be a non-starter.
JimRob should insist on some kind of veto power and in the case of a disagreement, he'll necessarily yank the authority to use the term.
In which case any ostensible leadership of the PAC will have to defer to the de-facto leader, and that will compliacte filings I suspect.
Another item to consider is: tax consequences to FR.
Will creating, supporting (on FR forums/threads/home page), “advertising the PAC” incur any tax consequences for JimRob?
IIRC, (from prior PAC research), the FEC reporting rules are very stringent and complex. I was advised that it is best to have either someone very experienced or a professional (CPA specializing in campaign finance) handling the job. I was referred to a CPA firm that does that for Republicans only, and was highly recommended. I will provide that if needed to whomever needs it.
As for a website for the PAC (or whatever we create), one idea is to have a list of all 100 Senators, broken into 3 groups according to re-election year (2012, 2014, 2016) and sorted by state within each group. Each senator could be color coded by party (red, blue) and then designated as RINO, CINO etc., with the senator name as a hot link to a page that lists reasons he/she is a RINO/CINO, etc.
