If you want the true math, then you need to realize that there is no way for the campaign or anyone for that matter to count delegates in states that haven't actually selected those delegates yet.
Iowa - 28 Delegates Total, 3 RNC (Unbound), 12 CD (Unbound) elected at CD Presidential Caucus on 4/21/12, 13 AL (Unbound) elected at State Convention 6/16/12.
Iowa Summary - There is no way to know the true delegate count for Iowa until after the State Convention on 6/16/12 and since ALL of Iowa's delegates are unbound, we won't know which delegates from Iowa vote for Ron Paul until the National Convention.
True Iowa Delegates for Ron Paul = 0 (same for every other candidate)
Speculated Iowa Delegates for Ron Paul = ???
NH - 12 Delegates Total (Rule 16 penalty -12 delegates), 12 proportionally bound delegates (10% threshold) elected at 1/8/2012 primary via candidate slate.
NH Summary - There is no special unbinding mechanism. Romney picked up 7 bound, Paul picked up 3 bound, Huntsman picked up 2 bound. Delegates bound to a candidate are (released) free to vote for who ever there next choice is.
True NH Delegates for Ron Paul - 3
Speculated Delegates for Ron Paul - ??? not less than 3 or more than 5
Minn - 40 Delegates Total, 3 RNC (Unbound), 24 CD (Unbound) elected at CD Convention 4/21/12, 13 AL (Unbound unless State Convention votes to bind) elected at State Convention on 5/5/12
Minn Summary - There is no way to no the true delegate count until after the CD and State Conventions. Again, we know that 27 and possible ALL delegates will enter the national convention unbound, so until that vote occurs and number can only be speculated.
True Minn Delegates for Ron Paul - 0 (same for every other candidate)
Speculated Delegates for Ron Paul - ???
Maine - Same story... for the sake of brevity, 5/5/12 is when Maine elects nation convention delegates. Since they are all unbound, there is just no way to know how many Ron Paul will have until they actually vote at the nation convention.
True Maine Delegates - 0 (Same for every other candidate)
Speculated Maine Delegates - ???
So unless you want to speculate, of all the states you mentioned, Ron Paul has a total of 3 THREE true delegates. I am sure there will be unbound delegates for Ron Paul who are going to vote for him at national convention. How many? We really can't begin to build a solid case until the process of delegate election is over in those states. Unless someone has a list of all the stage one delegate election processes for those states, there are 2 more stages to go, and those people would need to be contacted and then trusted to tell the truth about what they plan to do. PURE speculation at this point.
