Huckabee was second. He had 278 delegates, and Romney had 271.
Sad so many were fooled by him the first time.
As for poor Rudy, his high water mark was Florida, where he couldn't even crack 15% and walked away with zero delegates. Florida, like too many other states, uses a winner-take-all system in delgates. Pretty hosed, if you asked me, but that's the way it is.
The only conservative who won more than a single delegate was poor Fred Thompson, who managed to get 5 from Iowa and 3 each from Nevada and Wyoming. You can look it up here.
