“Jill Stein is a useful idiot for Russia. After parroting Kremlin talking points and being propped up by bad actors in 2016 she’s at it again,” DNC spokesman Matt Corridoni said in a statement to The Bulwark. “Jill Stein won’t become president, but her spoiler candidacy—that both the GOP and Putin have previously shown interest in—can help decide who wins. A vote for Stein is a vote for Trump.”
The whole point is that there is no challenge. It is sabotage funded by Republicans and Putin.
What challenges has she done when not running for POTUS?
