Nope. Your vote always counts. It may not feel like it counts much, it's one vote, but it will absolutely count. We have to stop this rhetoric of "my vote doesn't count" because it's how people justify not voting at all.
Especially from the "not trump" side of things, voter turnout is the only thing that stops them from winning. If you can give right/republicans one thing they have consistent voter turnout, but every single time overall voter counts are boosted (Like during Obama's initial election) the needle of results sways strongly towards Democrats/independents.
So please, please stop saying your vote doesn't count. Because even if it's a single vote it is SO important that you go and do it.
