Political Memes

This. If we're bringing math into this, then it's mathematically impossible for not voting / 3rd party to change anything in the same way calculus may not be 0 but near-zero enough to be indistinguishable. Combine FPTP with Electoral colleges with the power of existing political parties and the only way you're going to make change is by either one or both of the following things:

• Supporting one party so greatly you eradicate the other party, creating a vaccuum (eg, send GOP the way of the Whigs). In this situation, Democrats likely reconstitute themselves as the predominant center-right party while we get something of a social Democrat or true Green Party in their original place. A rubber-banding of the Overton window, if you will.

• Utilize an existing party to change the system. This means evolving the party, which for anyone old enough, recognizes how much Democrats have changed in the last 2 decades relative to the Republicans who have actually somehow managed to only get worse.

These are the only two proven methods to work. Third parties, Independents do not work until the system changes. And in order to change the game you need to first play by the rules of the game.
