I'm very surprised by Lauren Boebert's primary victory.
Colorado 4th Congressional District Primary Election Results 2024 - The New York Times
With 95% counted, she got 43.3% of the vote, with the others getting 14.5%, 13.7%, 10.8%, 10.6%, and 7.1%.
That means that 56.7% of the primary voters of CO-04 had voted against her, but her opponents were so divided that they let her win.
That's a problem with first-past-the-post or plurality voting: vote for one candidate and whoever has the most votes wins. Simple, but dumb. As this example shows, FPTP rewards the most unified political blocs, and that is why it produces a two-party system (Duverger's law). Here, LB was obviously very unified, since there is only one of her. But she had five opponents, and they did not try to consolidate their opposition by all but one dropping out.
An alternative has been emerging: ranked-choice voting. One ranks the candidates: first choice, second choice, etc. The votes are usually counted in instant-runoff fashion. Whoever gets a majority, more than 50%, wins, but without a majority, the candidate drops out who is in the fewest top choices. The ballots are then recounted as if that candidate was not in the race. This process is repeated until some candidate gets a majority of the remaining top-choice votes.
Thus, LB's opponents would have voted for one or two of LB's opposition as a second or third choice, and the survivor of these would have beaten LB.
