The democracy where dissidents get arrested and disappeared to extralegal foreign prisons or the one where they don't. Where autocratic leaders can get peacefully deposed or the one where they don't.
It's not about the policies of the democrats or republicans today. It's about any policy you want to enact by voting in the future.
My argument is you create a situation where democratic leadership either gets removed by intra-party politics and replaced by allies, or existing has no choice but to concede due to pressure from a large organized movement. Or likely some combination of those things. Honestly, I see this already happening to some extent but if more people were engaged in this strategy it would happen faster.
