I vote third party for every level cause where I live the only major party capable of winning is conservatives. Looking at the numbers, even if every single third party voter voted Dem, they'd still be 300-500k short or more to beat the conservative option. So voting for Dems here is literally no different than voting third party. Hell if they were even just 50k short of beating the Conservative party I'd start voting and supporting them, but there's literally no point.
