They are voting on different issues. On the first (or specified) ballot of voting for candidates is the ONLY time some are called bound. The NOMINATION is a different vote, and you need five states for that. While Romney and the party are frantically challenging all in credentials committees, Ron's states I would expect to be able to vote on the nomination are:
Minnesota
Maine
Iowa
Louisiana
Nevada
that is even if the Colorado alliance falls through where Santa bound delegates said they would vote for Ron.
Then for general motions there are a handful of other states where Ron has less than majority but a big chunk and would only need a few delegates bound to other candidates to support the issues Ron supports to be one of the SIX states needed to bring and second motions in general. Those include Colorado, Alaska, Virginia and if we get our delegates back, Massachusetts, possibly others. That is according to my tracking of them, in any event.
