Nope, that changed in 2008 to the way I described. There may be a portion that go to the statewide winner, but most are by district:
Here is a list summarizing what each state does:

How the heck will any of the 4 get to 1,144?
If they all stay in, with proportional allocation being dominant, they could all walk in the door with 400+.
There'll be fistfights in hallways!
What grand spectacle that would be.
for example, while Colorado and Minnesota have had their "beauty contest" caucuses, They still have NOT elected their delegates to Tampa. Both states go through a complicated multi-tier delegate selection process and a candidate who draws a bunch of neophytes (read "Santorum"), will usually have a harder time getting delegates to the top tier.
In Colorado,the party makes you pay (at the caucus, no credit cards) to be a candidate for delegate to the next level, lots of Rick's people didn't know this and left their checkbooks home. He'll still get a lot and COUL get a plurality, but I doubt it......he certainly will not sweep.
