She is doing fine. I like the way she is making sure to approach the main issues that voters are interested in and pushing them: women's rights, lower taxes on middle class, health care, how Trump killed immigration deal, supporting the actual constitution and unity abroad and at home and peeling away Republicans on the margins.
In the end, elections are decided on the issues. Trump can lie, but Harris just needs to keep pushing the truth. It will all come down to the ground game, and Harris has already built that. If the country actually wants the hate, chaos and authoritarianism Trump is pushing, then not much she can do about it
And I think Walz was a good pick.
