Warren is done after Super Tuesday. Not sure why I thought she'd be ok. During Super Tuesday the only states she'll do well in are her home state, California and possibly Maine and Vermont. I don't think she would do good enough in Virginia, Minnesota, and Colorado. Also it's a wrap for Warren in Arkansas, Alabama, Oklahoma, North Carolina, Tennessee, Texas and Utah.
Basically everyone is done after Super Tuesday except Bernie and Biden. I expect Biden to win the South, possibly Utah too. I expect Bernie to win the Northeast, win California and possibly win Texas or a close split with Biden.
