You can vote how you want. But in the two party system we effectively have in the US, not voting dem only makes sense if you really have no preferences between maga and dem. (Ie your ok with pedophiles running the country, destroying alliances, etc etc) And so if maga wins, unless you voted dem, you have not done what you could to stop them. So you are responsible for them winning and getting into power and all their policies. It sucks, but it's how it is. The key is understanding how although not perfect (possibly even bad), the dems are better than maga. Chose whatever you want - maga or dem.
