This is from what was given to me as being one of the best compilations of delegate and vote totals.
http://www.thegreenpapers.com/P12/R
Romney 1,841,731
Santorum 1,090,126
Gingrich 987,468
Paul 505,203
National delegates won't be assigned until June. They can't make a count.
My precinct straw poll was 56% for Romney.
But ALL 100% of the delegates are paul supporters. In one month we will go to our county convention and select delegates to the state. In June we will go to the state convention and select delegates for national.
The green papers are good but
popular vote isn't where to look, those numbers don't really matter (aside from perception/donations/momentum angles, basically PR)
Hard Total
Romney 118 5.16%
Santorum 17 0.74%
Newt 29 1.27%
Paul 8 0.35%
Those are the delegates that have actually been assigned to the national convention as of now. Of the total needed 1,144 national delegates.
The rest are not yet confirmed because the delegates assigned are on a more local level and have to work their way up through 'elimination rounds' to the state conventions which will then assign national delegates. These delegates will vote for whom ever they personally choose come convention time.
This is where Paul has a strong showing, understanding the 'game' he's prepared people so that they can secure these slots. Classic example is Minnesota where Santo won the Popular (straw) vote but Paul had the strongest showing in taking local delegates (which are the start of that process to elect national ones).
Now the above is a broad and general description because rules are unique to each state but that's a framework for how the process goes.
Bluntly when it comes convention time those delegates to the national convention are the votes that pick the Nominee and what the popular vote is or was won't direct or alter that (tho some individuals may choose to be 'advised' by it when they vote).
Hence the article I linked, it describes a bit of the 'how' of Paul taking full advantage of how the system is set up.
Regardless of what any of us think about the legitimacy of that system it is the one that is in place right now and the Official Campaign is taking whatever advantages they can be afforded by the rules in play.
