As “hardcore-left” as I am, I just cannot fathom, being so dumb to not vote “to show the dems”. The policies of bad Republican presidents hurt us till today. Think about Reagan vastly accelerating the gap between rich and poor, or Nixon with his failed war drugs.
Honestly unfortunately mostly unrealistic: a systemic chage towards deliberative democracy (not just USAs broken electoral democracy) would be the best according to most political science. It’s (way to) slowly happening in some European states (so the right shift may reverse that trend again). This indirection vie simple voting tends to lean towards populism and manipulation. Which got unfortunately incredibly obvious in the presidential election…
