They're both right-wing parties that don't give a fuck about the working class lol; they're on the same side.
And the supposedly "lesser evil" one is currently openly funding and supporting a genocide (even going as far as to bypass congress to do so) and is openly a zionazi.
There is no representation of the other (leftist) side in the US, and there will never be until the system itself, that's specifically designed to prevent that and serve Capital instead, is overthrown.
It's all one side. I know fans of each party like to twist themselves in knots to find daylight between them but outside of the culture war nonsense & which brand of idpol they subscribe to, the distance between them has only gotten smaller with every passing election in my lifetime.
The supposed solution to trump and the gop (who was labeled a dangerous madman that would get us into ww3) was to elect Biden and the Democrats
What has happened since?
Provoke Russia
Provoke China
Provoke Iran
Arm Nazis in Ukraine
Aid "Israel" in their genocide
All while their own citizens continue to struggle with basics like food & shelter.
Will republicans be happy to continue all of these? 100%. But let's not pretend there's some grand meaningful difference between them unless your most important issues fall within the category of the culture war in which case you must be doing pretty well.
If you actually compared the policy positions of both parties around foreign policy, taxation, healthcare, education, gun control.... the list goes on -- you would know that this argument is disingenuous at best.
At least one of the parties isn't trying to wipe LGBT people off the map. What you call "culture war nonsense" is a very real threat to those affected by the hundreds upon hundreds of legislation being proposed and passed every year
Both options on the ballot will be to support genocide. The GOP is very upfront about it. The Dems will pretend they feel very upset about it but they're still going to send the money and weapons anyway just like they're doing right now.
Unfortunately in this great "democracy" there's no options available for people who don't want to continue a genocide.
