@bobsal u1553115,
The Primaries are run by each party and they can set the rules however they see fit. The rules have nothing to do with the will of the People, it is the will of the Party.
Which is why I fundamentally hate the "party" system.
Yep, the system has been rigged forever.
"Men by their constitutions are naturally divided into two
parties: 1. Those who fear and distrust the people, and wish to
draw all powers from them into the hands of the higher classes.
2. Those who identify themselves with the people, have confidence
in them, cherish and consider them as the most honest and safe,
although not the most wise depositary of the public interests. In
every country these two parties exist, and in every one where they
are free to think, speak, and write, they will declare
themselves." --Thomas Jefferson to Henry Lee, 1824.
