The Green Party candidate has around 1 percent of the vote, which Democrats fear could disrupt the razor-thin margins in this year's election.

Democrats launched a six-figure ad in Wisconsin Friday, highlighting how Stein could hand Donald Trump the White House.

The non-major-party vote is likely to be small this year, but as 2016 showed, every vote matters in battleground states.

Stein is only polling near 1 percent in most polls, but Harris advisers fear even that margin could prove decisive in race against Trump.

Ohio Secretary of State Frank LaRose’s office disqualified the Green Party presidential nominee after getting a withdrawal letter from Stein’s running mate. But Stein’s campaign claims the letter was written behind the candidate’s back.

The ad comes as the Harris campaign has repeatedly accused Stein of being “propped up” by Republicans in an attempt to swing the election in Trump’s favor.

Not only is she helping Trump win—she’s destroying a once-noble party that could be doing good in this country.

The ad cites reporting out of the Wall Street Journal that says Republicans are boosting Stein and quotes Trump saying he likes Jill Stein.

Stein has been a perennial candidate who also ran on the Green Party ticket in 2016 and 2012. Her campaign has focused on opposition to U.S. support for Israel in its brutal war in Gaza, calling it a “genocide” and Israeli Prime Minister Benjamin Netanyahu a “war criminal.”

Green Party presidential candidate Jill Stein has filed a lawsuit in federal court over the decision of Ohio election officials not to count votes for her after her running mate was named by the national party after a state administrative deadline.

In every battleground state this year, there is at least one third-party or independent candidate on the ballot. The Democrats have been more openly concerned than Republicans.
