It's a welcome change, but she still isn't firm enough. To make her message more firm:

1. The first paragraph needs to be taken out. You can't say voting is pointless (true) while hyping up this election at the same time.

2. "There is no doubt that one of the candidates - Trump - is way more dangerous than the other." That's just her capitulating to lesser-evilers. Trump isn't "way more dangerous" than Harris at all outside of him being a shittier imperialist to the imperialist project. As Black revolutionary Imam Jamil Al-Amin said, "Evil is evil. There's nothing in between that."

3. "With this in mind, my main message to Americans is to remember that you cannot only settle for the least worst option." She needs to get rid of the "only."

To me, it looks like either her original message was a lot firmer but got watered down by one of her close associates who changed her mind/edited the message or she is personally conflicted and hasn't fully crossed the bridge to give up on lesser-evilism.
