Americans haven't elected an independent president since George Washington, but a public turned off by two historically unpopular frontrunners appears more open than ever to the rich crop of wildcards who could tilt the election in 2024.

Voters have made clear in multiple polls that they don't want a rematch between Joe Biden and Donald Trump, and are willing to take a serious look at the growing number of politicians mulling independent or third-party campaigns.

None has much of a chance of winning the White House in November but several so-called "spoilers" could sway a close election in either direction, say analysts.

Democrats in particular fear a wildcard candidate harming their prospects, recalling how Green Party standard-bearer Jill Stein threw a spanner in the works for Hillary Clinton in 2016.

Stein is running again alongside several hopefuls seeking to upend the two-party system, such as racial justice activist Cornel West and Robert F. Kennedy Jr, a candidate with a famous name who poses the biggest threat to the status quo.
