I think I understand why you’re not getting this. You simply can’t understand that under FPTP, the only way to vehemently deny one candidate and to keep them out of office is to ‘support’ the other, even if you don’t agree with them. When one candidate will destroy democracy and usher in an autocracy, if you actually care about having a choice in the future, the only effective solution is to support an opposition that will not destroy everything.
You still haven't addressed how Biden's foreign policy and Harris's presumed foreign policy (due to her unwillingness to create daylight) isn't a part of her platform aligned with the Cheneys.
This is not the topic of conversation, and I’ve already given you enough of my time. Google exists., and I’m not your polisci professor. You can look the rest up for yourself.
This is exactly the reason. Because saving democracy right now means getting every possible vote, and the Cheneys can sway some old, Reagan/Bush republicans who reflexively vote R without really paying attention. If even the Cheneys support Harris, they might take notice. It’s an enemy-of-my-enemy situation.
