Being real though, Harris doesn't need to focus on trans support. It's one of the few issues where she's got such a strong track record that even far lefties like me can manage to trust that she won't back down when it comes time to exercise president powers.
By not using trans rights as a stump point, she lets the far right idiots and bigots out there do the work of shooting themselves in the foot with the hate. If Harris started preaching hard on the issue it sets her up to be a single rallying point for the bigots. It turns the election into that issue, which buries all the other insanity that the far right wants.
Yeah, it will be nice when politicians actually speak out clearly on trans rights. It's always a good thing. It just isn't necessary to still achieve a victory for rights, which is the important part.
Fwiw, the article essentially says all of that with different emphasis, I'm just expressing my take on the matter.
Also fwiw, there's a shit ton of us out here that are sick of the bigotry and bullshit being pushed about trans folks. We'll be voting accordingly, but I sometimes think it useful to say it as well. We know every trans person out there is deserving of respect, love, and equality under the law, and we won't give up on that.
