The impact of independent Robert F. Kennedy Jr. suspending his presidential campaign Friday and endorsing Donald Trump remains to be seen.
It’s more likely to be a boon to Trump than to Vice President Kamala Harris, given Kennedy was drawing significantly more votes from the right and from would-be Trump supporters. But Kennedy’s share of the vote was at about 5 percent and falling.
One thing that’s relatively evident, though: To the extent the remaining third-party and independent candidates pull votes and even potentially play spoilers, it appears more likely to be at Harris’s expense.
Kennedy’s exit leaves three significant names below Trump and Harris on at least some state ballots: Green Party candidate Jill Stein, Libertarian Party candidate Chase Oliver and independent Cornel West.
All three come from left-leaning backgrounds. Stein and West are both generally further to the political left than Harris. Oliver’s potential appeal is harder to define, as it often is with Libertarians. But he’s a former Democrat and left-leaning Libertarian who defeated a more right-wing candidate at May’s Libertarian National Convention.
