If a low six figure number of people in a handful of states had voted last fall, none of the lawlessness that we’ve seen this year would have happened. The people telling you that voting is useless are enjoying the fruits of suckers believing them.
The key part being "in a handful of states". There are many states in the country in which your vote is all but meaningless at the federal level. The Electoral College + relentless Gerrymandering that has been done over the past decades ensures that only a small fraction of eligible voters can cast meaningful votes. Makes it much easier to target and propagadandize those smaller groups. We saw it play out with Cambridge Analytica, but there hasn't been another "scandal" of that sort because it's just established practice now. Everyone has their hand in the pot doing the same thing, it's all above belt.
You should still vote, because you can enact change at the local + state levels, but the levers of federal power have been taken from the people.
See? Same facts, but culminating in a call to action based on the premise that is affirmative of the value of democracy. If there was one person who mobilized this way for every ten who gave up in resignation it would be done already. But the battle against hedonic skepticism is hard.
Second, while some states may be unlikely to change their choice of president or senator, the local level matters quite a lot AND that’s where electoral reform will happen. If you don’t like the two party status quo, if you don’t like the electoral college, giving up on voting ensures defeat whereas supporting things like ranked-choice voting or the The National Popular Vote reform.
That also happens to be what the people in power would like you to believe.
