If somebody criticizes Harris’s platform in support of Trump, there is a 99% probability that they would support Trump no matter what her platform is, details are irrelevant. They’re just making excuses to vote for him.

Trump tried overflowing the election results - there is no ambiguity about that. If somebody still supports him, they can’t be trusted. Debating anything with them is like debating with a flat Earther, it’s a complete waste of time,. They probably still support him because they don’t want to admit they get conned, or being a Trump supporter is simple their identity, etc
