You didn't vote for the person but for an alternative. This is "doing something to stop them from winning."
I didn't say it wasn't "doing something." It was. And i commend it.
But it wasn't "doing the most you could do to prevent him from winning." Clearly voting for the other candidate who had a chance of beating Trump is doing more to stop him from winning than voting for someone with zero chance of winning. I don't know who could even debate that point. And please don't twist this into me somehow saying you should only vote for people who can win; that's not at all what i'm saying, i'm just saying that in the context of solely trying to deny Trump a presidency, the ability of an opponent to win must be factored in.
I threw away my principles and voted for someone i didn't like because i wanted to do everything in my power to deny Trump a win. Voting for someone else who happens to not be Trump does not have the same preventative power. Kudos to you for sticking with your principles - my discarding them didn't get me anywhere - but please don't pretend you did everything you could to prevent a Trump presidency, because you didn't.
