re: #80 gehazi
I had a hard time tracking down the information, but the proportional representation thing only applies to pre-April primaries and states are allowed to apply floors below which a candidate will not get any delegates. Apparently the details are up to individual states, but I expect many to establish floors in the 10-15% range, specifically to target people like Luap Nor Rm.
From this RNC memo:
Use this link, it breaks things down nicely. You’ll see that most of the states having primaries after April 1 still do some form of proportional.
