As a leftist I was critical of Biden and continued to be critical of Harris, despite hating Trump even moreso.
It’s not suspicious, it’s consistent based on our ideology.
As I’ve said elsewhere I’m an expat not a resident, so I mostly vote here in Canada, and I don’t really like any of my 3 main options right now. I’ll strategically vote to keep the Conservatives out, but that doesn’t mean I like the Liberals and I’m comfortable criticising Trudeau.
