Says Perkins, in descending order:

Romney - 1595
Huckabee - 1565
Ron Paul - 865
Thompson - 564

5,776 votes cast. Many online, hence Paul...

Update:

On-site, as opposed to combined on-site and online, numbers are interesting:

Huckabee - 488
Romney - 99
Thompson - 77
Tancredo - 65
Giuliani - 60
Hunter - 54
McCain - 30

950 votes cast.
