People frequently make this statement and I think it’s wrong at face value.
If you vote you are giving legitimacy to the beltway uniparty. If the election is “free and fair” why does voting give you the right to complain?
But talking about "beltway uniparty" is indicative of a level of lacking intellectual curiosity that's genuinely sad. You can do better than that.
Maybe if this was twitter or a dinner party and you're just going for cheap laughs, sure, whatever, but I dunno, I guess this place isn't much different? Maybe it could be though?
I'm not saying I need to agree with everything a candidate says, or even most of it. I need to at least believe that we won't be worse off as a country with the candidate I vote for. I can't sat that for Trump, couldn't say that for Biden, and wouldnt say that for Harris if she is selected.
