My understanding is that the SEC primary is all proportional. They winner take all states don’t commence until March 15.
Nope...five or six of the super Tuesday States have a 50% threshold that if any candidate achieves...they get all of the delegates. Up to 50% it is proportional, after that its winner take all.
The first full winner take all if on the 15th with FL and OH.
Actually, there are only about a dozen true "winner-take-all" states. The rest are either proportional (usually with some threshold for getting delegates) or are a hybrid, with the winner of each congressional district getting delegates, and with the overall state winner getting additional delegates. That is why it is going to be hard for anyone to get a majority of delegates before the convention if we have a three-way race.
I think SC is an exception, for some reason. I’m seeing they are winner take all.
