I expect the mainstream US media to struggle with the concept of proportionality. But even FiveThirtyEight, which prides itself on brining quantitative methods to election coverage, can’t get this right.
Sure, far more delegates were at stake on Super Tuesday (595) than will be awarded March 15 (367), but the Super Tuesday delegates were all awarded proportionally.
If that was the case, then I’d like to ask how it is that Ted Cruz got 2/3 of the Texas delegates on 43.8% of the votes. Or how Donald Trump got 73% of delegates in Alabama on 43.4% of votes. There are several other examples, but I hope these two suffice to make the evidently very difficult point.
