I don't think "ninja delegates" are even obligated to vote for any candidate during the first round. They are pledged, but I imagine they can cast their vote for whoever they want. I.e. most delegates vote for the winning candidate at the convention in a show of party unity.
What if they make a commotion by wearing pro-Paul clothing, or shout, or do something silly like that? Is there a good chance the majority of delegates are going to be Paul affiliated chosen ones, because this is now starting to worry me if it distracts from the Convention's focus on Obama.
