1. No candidate including Warren looks at their own twitter.
2. Snake memes started very near the end of Jan, coud something have preceded them? Something that dominated the news cycle before the 1st caucus and was talked about in the debate?
3. As we can see from 4 different states and from polling, Warren's base is wealthy white people with college-degrres. Bernie's base is multi-racial (disporportionately Latino) and young. There is some overlap but not much - Warren is taking enough young women to make Bernie's job very difficult, but the rest of her voters probably aren't winnable.
4. Good that you acknowledged that her campaign is explicitly against him, because at this point that's what it is. It is not to become president, it is not against Biden who shares 0% of her base, it is to stop Bernie.
5. Twitter isn't real life either.
6. She raised her best amount of money (24m), and has now got the support of the largest Super PAC in the race, enough to keep her going till end March.
She needs to be defeated if Bernie is the nominee. I hope, like
@Fergie's gum said, that a humiliation in her home state is enough.
