predicted Stein may not earn as many votes in 2024 as she did in 2016 when she “benefitted from progressives’s dissatisfaction with the political establishment,” particularly now that demographic appears “newly energized by the Harris campaign.”

So the article points out both a hope for Harris supporters and also a valid counterargument to their strategy of trying to keep Stein off the ballot.

“This election is different than 2016,” a longtime Michigan Democratic activist told the Washington Examiner. “Both Stein and West are threats to Harris in Michigan because they are appealing to Arab American voters upset over the Biden administration’s Middle East policy to vote for them rather than Harris.”

“Studies of Stein voters show that many of them would have not voted or would have supported Trump had the Green Party candidate not been on the ballot,” Burden said. “Memories of 2016 also ignore that the Libertarian ticket drew even more votes than Stein and probably hurt Trump more than Stein hurt Clinton.”

I.e. in other words, instead of trying to keep Stein off the ballot (and offending these folks into staying home and not voting) Dems would be better off actually trying to win these folks votes by engaging with them and trying to give them what they want.

So again, hope for the Harris campaign, especially with the recent endorsement of Emgage Action, that these voters can still be won over at the last minute.
