Unlikely since Stein and Oliver both draw from different groups.

Here's how PA played out in 2020:

https://en.m.wikipedia.org/wiki/2020_United_States_presidential_election_in_Pennsylvania

Democratic - Joe Biden - 3,458,229 - 50.01%
Republican - Donald Trump - 3,377,674 - 48.84%
Libertarian - Jo Jorgensen - 79,380 - 1.15%

The Greens didn't even rate. But assuming the Libertarian votes (Oliver's party this time) would have all gone to Trump, that still wouldn't have been enough to flip the election. 3,457,054

kamala knows what she needs to do to win those votes. balls in her court...

Oh no, what can the Kamala campaign possibly do about it?

Dangit if only there was some incredibly popular thing Kamala could do to win over all those independent voters

As a progressive living in Pennsylvania, I don't know anybody who is voting for Stein, and I don't even know who Chase Oliver is. I know more people who still plan to vote for RFK and those people are batshit insane.

I have plenty to complain about with Harris, and I want her to keep campaigning here, but I am cautiously optimistic. I don't claim to have polling data, just the general buzz among the Green Party members I know and awareness of lawn signs. So take that with a huge grain of salt.

Stein's campaign is right about this:

"In a democracy, no one owns your vote, candidates need to earn your vote, and the only 'spoilers' are the political elites who work overtime to deny a meaningful democratic choice to voters who are hungry for real choice..."

What has Jill Stein done to earn your vote, though? Viability is a big part of that. If I could snap my fingers and institute STAR voting tomorrow, we would be having a different conversation. Yes, we want better politicians and policies, but if you don't think that the choice between Harris and Donald Fucking Trump is meaningful, then you've got your head entirely up your own ass.

Harris doesn't get my vote because I owe it to the Blue Team. She gets my vote because she's a reasonable adult running against a violent madman, and she's the only candidate who can stop him.

Jill Stein is nothing. She's a joke, and likely funded by Russian oligarchs hoping to help Trump.
