I went ahead and watched both nights of the first Democratic debates, and in light of performances and new information circulating Twitter following said debates, I had to make a couple updates to the grades I've given candidates I've already reviewed.
Tulsi Gabbard: B+ ----> F
As hot as that gray in her hair was, Tulsi apparently has many fans among the alt-right and made an entire video that she posted to Twitter about how Mueller said no collusion. Since he definitely didn't say that and also WTF TULSI, I had to give her an F.
Julian Castro: D ----> C
I had originally given Castro a D largely due to what seemed like a "lack of effort," which I don't really understand now, but remember that these grades are completely non-scientific and largely subject to my whims and moods. It's not like I'm getting paid for this. Anyway, Castro may still be a capitalist but he put effort into that debate and impressed me by mentioning non-binary people (I don't know that any Democrat has done that in an official presidential debate) and for laying out a bold immigration plan that demonstrated research and understanding and that he absolutely wants to shut down the concentration camps. C, and I'm open to bumping that up further.
Marianne Williamson: A- ----> F
Another F. Because, of course, after the weirdness she demonstrated during the debate, everyone is looking into her, doing much better research that I did, and it turns out she sucks. Oh, and she revealed herself to be an anti-vaxxer like five days ago. No amount of advocating for reparations can make up for that bullshit.
