I wish American Voters had memories longer than 4 years. But they don't.
They got pissed at Bush and the Republicans in 2006 for the war and in 2008 for crashing the economy.
And 2 years later in 2010 they voted in a red wave not seen since reconstruction.
Donald Trump tried to overthrow the government and 4 years later they gave him another chance. If Trump shot a crowd of people on 5th avenue the kids of the victims would vote for him 4 years later.
There were massive voter suppression campaigns in both those election cycles. And it doesn't help that the neo Liberals highjacked the democratic party, marginalizing labor. People are not motivated to vote for the lesser of two evils.

Neoliberals and centrists need to get this through their firewall of condescencion towards leftists, no matter how much y'all hate leftists (and laugh at leftists with your more conservative friends) you need to understand the average person in the US hates you and your leaders far more than than they hate genuine leftists that actually fight for the working class instead of spitting on them and publicly calling them stupid.
Democracy will not save us. People that won't vote unless they fall in love can fall out of love much more easily.
Do vote, it's low effort and it can make a marginal difference. Just make your plans assuming you party will lose and if they win they will disappoint.
Keep in mind that the voting system itself is rigged. States with lower populations tend to have more representation per capita due to the Electoral College. This biases everything towards red states.
And that doesn't even get at the decades of gerrymandering...
Your treating this as if the same people are voting different ways. It's usually much more along the lines of voters staying home one election and voting in another.
