Italo Medelius was leading a volunteer drive to put Cornel West on North Carolina’s presidential ballot last spring when he received an unexpected call from a man named Paul who said he wanted to help.

Though Medelius, co-chairman of West’s “Justice for All Party,” welcomed the assistance, the offer would complicate his life, provoking threats and drawing him into a state election board investigation of the motivations, backgrounds and suspect tactics of his new allies.

His is not an isolated case.

Across the country, a network of Republican political operatives, lawyers, and their allies is trying to shape November’s election in ways that favor former President Donald Trump. Their goal is to prop up third-party candidates such as West who offer liberal voters an alternative that could siphon away support from Vice President Kamala Harris, the Democratic nominee.

It is not clear who is paying for the effort, but it could be impactful in states that were decided by minuscule margins in the 2020 election won by Democrat Joe Biden.

This is money West’s campaign does not have, and he has encouraged the effort. Last month, the academic told The Associated Press that “American politics is a highly gangster-like activity” and he “just wanted to get on that ballot.”

Trump has offered praise for West, calling him “one of my favorite candidates.” Another is Green Party candidate Jill Stein. Trump favors both for the same reason. “I like her very much. You know why? She takes 100% from them. He takes 100%.”

Democrats are exploring ways to lift Randall Terry, an anti-abortion presidential candidate for the Constitution Party, believing he could draw voters from Trump.

But the GOP effort appears to be more far-reaching. After years of Trump accusing Democrats of “rigging” elections, it is his allies who are now mounting a sprawling and at times deceptive campaign to tilt the vote in his favor.

“The fact that either of the two major parties would attempt financially and otherwise to support a third-party spoiler candidate as part of its effort to win is an unfortunate byproduct” of current election laws “that facilitate spoilers,” said Edward B. Foley, a law professor who leads Ohio State University’s election law program. “This phenomenon is equally problematic whichever of the two major party engages in it.”

One key figure in the push is Paul Hamrick, the man on the other end of the call with Medelius in North Carolina.

Hamrick serves as counsel for the Virginia-based nonprofit People Over Party, which has pushed to get West on the ballot in various states across the country.
