With Robert F. Kennedy Jr. stepping away from his independent presidential bid and endorsing Donald Trump, the dynamics of the 2024 election have shifted, particularly in the context of potential spoiler effects. Initially, Kennedy’s candidacy had drawn notable support from conservative and right-leaning voters—those who might otherwise back Trump. But with Kennedy out of the picture, the focus now turns to a trio of candidates from the political left who could alter the race’s trajectory: Jill Stein of the Green Party, Libertarian Chase Oliver, and independent Cornel West.
The “spoiler effect” is a phenomenon where third-party or independent candidates siphon just enough votes from major-party contenders to influence the election’s outcome. Historically, this effect has often been viewed through a right-left balance. However, Kennedy’s exit disrupts that equation, leaving the left more vulnerable to vote splitting.
A Left-Leaning Slate
Jill Stein, the Green Party stalwart, and Cornel West, a progressive icon, both represent leftist ideologies that could attract voters who lean more liberal than the mainstream Democratic ticket. Chase Oliver, while a Libertarian, leans left on various issues and could also draw support from disillusioned Democrats. Unlike the mixed ideological appeal of previous Libertarian candidates, Oliver’s background as a former Democrat and left-leaning Libertarian gives him a unique edge in capturing liberal votes.
Polls already indicate a modest yet meaningful trend. In surveys, Stein and West consistently pull more from Democratic-leaning voters than Republican ones, posing a potential threat to Kamala Harris’s prospects in a close race. Though their support hovers around 1 percent, even small numbers could make a big difference in battleground states where margins of victory are razor-thin.
The Ghost of 2016: Will History Repeat?
The lingering specter of the 2016 election haunts Democratic strategists, where some argued that Stein’s Green Party run drew away enough left-leaning votes to cost Hillary Clinton key states. While this narrative is debated, the current landscape suggests a similar risk in 2024—one where left-wing candidates could once again play spoiler.
This time, however, the threat is compounded by the absence of a counterbalancing figure like Libertarian Gary Johnson in 2016, who attracted right-leaning voters. With Kennedy gone, the third-party field is skewed more heavily toward the left, amplifying the risk that liberal voters, dissatisfied with the Democratic ticket, could split the vote and hand victory to Trump.
The Unpredictability of 2024
Despite these concerns, the spoiler effect is notoriously hard to predict. While polls provide some insight, the actual behavior of voters on Election Day can be erratic. Many third-party supporters might ultimately stay home if they feel their preferred candidate has no real shot at winning, mitigating their impact on the final results.
Additionally, ballot access issues could limit the reach of these candidates. Stein is still working to get on the ballot in swing states, while West faces legal battles over his place on certain state ballots. Oliver, as the Libertarian nominee, has broader ballot access, but his appeal remains unpredictable and could vary depending on the political environment in different states.
A Leftward Shift in the Spoiler Equation
As the race intensifies, the 2024 spoiler effect is increasingly tilting leftward. With Kennedy no longer pulling from Trump’s base, the burden of potential vote-splitting falls on Stein, West, and Oliver—each of whom could peel away critical support from Kamala Harris. The stakes are high, and in an election that could come down to razor-thin margins, the influence of these third-party candidates cannot be ignored. Their combined impact may very well shape the course of the election, turning what was once a balanced spoiler equation into a potential advantage for Trump.
