We know this.
In an electoral college system, only swing states matter.
But parties will pay attention if votes are siphoned from them. If you’re not in a swing state, a third party vote has basically no negative effect but may have a positive effect of influencing a major party.
I think it’s more than arguable that voting for Kamala in Louisiana or Mississippi or even potentially California is a bigger waste of a vote than voting third party.
Right? Imagine believing there are enough conscientious progressives / leftists to flip CA red because of third party voting. Sure, Jan.
