This primary season has received a great deal of attention, and with it, the various ways states handle their delegates has received a lot more press. In particular, Colorado saw Ted Cruz beat Donald Trump strongly, collecting all 34 delegates.
However, this was not a typical primary election. Last summer, Colorado changed its rules. In essence, the state’s delegates did not want to commit to a candidate who may not last through the primaries to the convention. So, they adopted a new process, which involved a caucus that gave an extreme amount of weight to party insiders, leaving the majority of Republican voters out.
In response to the new process and the loss, Trump tweeted "How is it possible that the people of the great State of Colorado never got to vote in the Republican Primary? Great anger — totally unfair!" He also said, "The people of Colorado had their vote taken away from them by the phony politicians. Biggest story in politics. This will not be allowed!"
While this difference in rules does seem strange and unfair, both Republican Party officials and Ted Cruz have pointed out that this change was known far in advance, and Trump did not change his strategy. Cruz, on the other hand, had been working hard to obtain these delegates within the new system, while Trump only got staffers into the state a week before the results came in.
In all, the rules were known in advance, so it’s difficult for Trump to argue in that sense. However, shifting away from a standard primary or caucus to a pick by insiders is certainly grounds for anger, both within the camps of the Trump campaign and the Colorado voters.
