The calendar is

2/3 - Iowa

2/11 - New Hampshire

2/22 - South Carolina

2/29 - Nevada

And then we have March 3 with a ton of states including California, which is the real prize that day. The last poll from California shows Warren leading by 15% over Biden.

If she wins Iowa and New Hampshire, he's going to start bleeding some of his support in South Carolina. He'll still win the state and by a large margin. I still favor Biden as the favor in Nevada, as the overwhelming majority of the vote comes from Las Vegas and the casino bosses pretty much control the vote of their employees.

But Warren has to be pleased with where she stands. If she goes into March 3rd 2-2 she's going to be moving in the right direction with a boatload of California delegates headed her way, and he's in a fight for his political life.
