Water is discussing:

Tulsi is the most sane of all the Democratic candidates. But there's a very real danger that she only looks sane by comparison, because she's speaking up on the ideas where she differs from the other candidates because she's trying to stand out.

Remember in 2016 when Bernie Sanders looked like the sane Democratic candidate in comparison to Hillary Clinton? He undoubtedly was, but he's since gone on to say gems like 'When you're white ... you don't know what it's like to be poor' and "Fossil fuel executives should be criminally prosecuted for the destruction they have knowingly caused. #GreenNewDeal". Is that who you would have wanted as president?

Tulsi is just the lesser of two (dozen) evils.
