For those who read Jill’s post below this one, please be advised that Ron Nehring’s proposal has now been altered to provide that any participant in a caucus who is away, on active duty, may have an alternative represent them. So while there are differences between the plan, both plans address the concern about active duty military personnel.
Clearly some electioneering was going on, as no attempt was made to get Nehring to take care of this concern before "going public" — this was just an effort to attack the Nehring plan. Nevertheless — the issue has now been addressed and is moot.
