Should ranked-choice voting be adopted nationwide?

Ranked-choice voting (RCV) has gained momentum as a potential cure for polarization and two-party gridlock. Alaska and New York City have implemented it, with promising early results. But there are legitimate concerns: complexity for voters, tabulation costs, and the "bullet voting" problem where voters still default to their first choice. What's the case for RCV? It eliminates the "spoiler effect," rewards consensus-building, and lets voters express genuine preferences without fear. What's the case against? It could amplify fringe candidates, ballot patterns in Alaska suggest most voters still bullet-vote anyway, and implementation is genuinely complicated. Should the U.S. move toward RCV, or are there better voting systems worth considering?
