I wonder why they are ignoring Missouri and NC? Those are winner take all too, right?
North Carolina is proportional. Missouri is hybrid, by congressional district.
North Carolina is strictly proportional (each candidate gets 1 delegate for every 1.38% of the statewide vote.)
Missouri is winner-take-all if a candidate gets over 50% statewide. Otherwise, each Congressional District is worth 5 delegates and the overall state winner gets a pool of 12 additional candidates.
Illinois gives 3 delegates for each Congressional District and 15 delegates for the statewide winner.
Only Ohio and Florida are winner-take-all across the board.
FL, and OH are Winner Take All.
MO is winner take all if winner gets 50 percent or more, otherwise it is proportional based on Winner Take All by congressional district.
IL is Statewide delegates are winner take all, congressional district delegates elected directly on ballot and bound as they declare
NC is proportional.
Missouri is winner-take-all with 52 delegates. (Ohio has 63).
North Carolina is proportional according to the statewide vote, with no minimum.
As others have noted, if Trump gets Florida, Ohio, and Missouri, and makes a strong showing in NC, the race is effectively over.
The most Cruz would be able to do at that point is get enough delegates to deny Trump the first-ballot nomination, and let the Establishment hand it to Romney.
Because FloriDUH, Ohio and Illinois are 1,2 and 3 for the highest delegate totals up for grabs on Tuesday.
