They didn't vote for Trump, so now what? People that try to paint people into a political corner should really get out more. Not only is it annoying and off-putting, it's an intellectual dead end.
I know a lot of staunch libertarians, and maybe 20% (if that) voted for Trump. And of that 20%, about 95% were voting for him because they accepted the false dichotomy of Kamala or Trump.
There are plenty of valid criticisms of libertarians IMHO, but supporting Trump isn't really one of them.
Most of the libertarians I know voted for trump and pretend that they did so to vote against Harris. But that’s probably because they don’t want to take responsibility for what the voted into office.
