There's no telling what the 2024 presidential general election is going to look like after what will probably seem like an endless campaign between Joe Biden and Donald Trump. But both the early polls and recent history suggest that the contest will be close, just like six of the last seven presidential elections. Thanks to widespread disgruntlement with this choice, the odds are also high that the non-major-party vote will be relatively high (more like 2016's 5.7 percent than 2020's 1.9 percent) - and that may decide the election.
