I have a new opinion piece at Reuters, "GOP Nomination Process 101: Candidate's Remedial Edition." It begins:

Donald Trump has complained that the Republican primary process is a “rigged, disgusting, dirty system” that deprives people of the chance to vote for their preferred presidential candidate. He accuses the Republican Party of stealing delegates from him.

If he thinks this system is complex, Trump should look to the GOP’s past primary elections. Now, those were complicated!
