They booed former President Donald Trump, the Republican presidential candidate who currently leads in polling in some swing states. They rejected Robert F. Kennedy Jr., the independent candidate who is polling at 15% in some polls.
I'd prefer Approval Voting, RCV has really been over-sold and it practically the same to FPTP anyway. In RCV elections, the first round winner ultimately wins the race 96% of the time. That article tries to claim it somehow makes a difference in campaigns, but in a practical sense, it doesn't. Campaigns rarely say "rank me second," because of course not. Who would aim for second place? It also has unfortunate consequences with disenfranchising poor and minority communities, because they end up submitting invalid ballots at a significantly higher rate.
Anyway, so if you're all like "stop attacking RCV it's better than FPTP!" Well, I agree, but use that energy to run a referendum campaign and switch your local elections to Approval Voting instead. It's used in both Fargo and St. Louis and we're seeing the same positive effects that RCV has without the voter disenfranchisement.
Unfortunately our democracy is flawed, and our election system punishes similar candidates who run against each other in the general election.
Because of this, our political parties are more like coalitions, made up various groups with overlapping goals, who choose one candidate through a primary, so that they don’t cannibalize each other in the general election.
This means that those who run third party anyway are either looking for publicity, cynically playing the spoiler, or fools.
