I was at the Douglas County convention, too. It's tough to try to estimate, but my guess is that we got approx. 30 out of the 108 state delegates. So we have roughly 25%-28% of the Douglas delegation.
Again, that's only a guess and I welcome an upward revision of that estimation, but even 25% is pretty good considering Ron Paul only got 5% of the Feb 4 straw poll.
