That makes an assumption that all or a big majority third party voters would prefer Harris over Trump.
Just for clarifying the logic here.
Nobody who would have otherwise voted for Trump is going to be convinced to vote for Stein. Every vote she gets IS one that was much more aligned with Harris.
This isn’t a question of ALL third parties, but there aren’t any right-aligned third parties making any kind of a meaningful run.
What??
In Michigan Gary Johnson got 172,136 votes, in Pennsylvania he got 146,715, and in Wisconsin he got 106,674. If all Greens voted Clinton and all Libertarians voted Trump then New Mexico would’ve only been won by Clinton with around 1,000 votes, Colorado would’ve also been nearly Trump. Nevada, New Hampshire, and Minnesota would’ve been won by Trump. Maine might’ve gone majority Trump.
Third parties hurt Trump more than they help him, because Libertarians would not have voted Clinton.
The Green Party is far more left-wing than the Libertarian Party is right-wing.
And how many of them are running now? This isn’t about them, this is about the one third party candidate that actually makes headlines.
