A Trump supporter from Colorado is not happy with the Republican Party. And for good reason. Instead of conducting a primary election or a caucus, which would give regular voters the opportunity to vote for the next president of the United States, the Republican Party of Colorado chose to hold only a state convention. At a state convention, only party insiders are invited to attend and the rules are governed exclusively by the party leadership.
At the convention, party insiders gave all of the state's 34 delegates to Ted Cruz, without a vote.
It should be little surprise that this Colorado voter is fed up with the Republican Party. Their opinion literally does not matter. Because Colorado did not hold a primary or caucus, the average voter is completely removed from the process.
In statewide elections, Colorado has a closed primary system. By burning his party registration, he joins the 37% of the state that have taken the effort to register to vote, but would rather not have the right to vote in primaries than affiliate with either of the major parties.
