I think politics need to be interesting for people to vote. If the expected outcome is that everything only worsens a bit, you’ll never get people to vote for you. So by leaning right, she basically tried to appease the conservatives, but made progressives lose interest. I don’t think that anyone (or a substancial number) on the left tried to “own” her.

Hopefully there will be next elections, and hopefully there will be a party worthy of voting for it.
