TBO = The Big One 3/3 Super Tuesday

There is not a lot of polling data out there according to Real Clear Politics.

What is the polling data saying?

California - Sanders is set to win, the question is whether anyone else will clear the 15% needed to snag some delegates. Biden needs to get over 15% and better yet 20%.

Texas - Sanders has a slim lead but it is within the margin of error and will be a key state to watch. Hence, Biden is getting Senator Amy and Mayor Pete to appear with him in a rally in Texas tonight. If this works, Biden gets the first down to keep the drive going.

North Carolina - Biden has a slim lead but it is within the margin of error and another key state to watch.

Virginia - the polling report at RCP is a bit out dated so it is hard to say what is going on there and another key state to watch

States Biden should win

1. Alabama (52) - no polling data but a southern state where Biden should do well
2. Arkansas (31) - no polling data but a southern state where Biden should do well
3. Tennessee (64) - no polling data but a southern state where Biden should do well

States Sanders should win

1. California (415) - polling data in favor of Sanders
2. Colorado (67) - no polling data but Sanders won easily in 2016
3. Maine (24) - no polling data but Sanders from nearby Vermont
4. Massachusetts (91) - Warren's home state but will she beat out Sanders?
5. Minnesota (75) - Klobuchar home state but will she beat out Sanders?
6. Oklahoma (37) - no polling data but Sanders won easily in 2016
7. Vermont (16) - no polling data but Sander's home state
8. Utah (29) - no polling data but Sanders won easily in 2016

As you can see, there are six states where Sanders is likely to win and two where he will probably finish a strong second.

Unknown

1. American Samoa (6) - Is it controlled by the Democratic establishment? If yes, Biden should win
2. North Carolina (110) - close in the polls
3. Texas (228) - close in the polls
4. Virginia (99) - close in the polls

Biden will need to win these four to keep the race close. 

Bloomberg is a wild card. It would be terribly ironic if a multi-billionaire is the reason the Democrats win up with Sanders as the nominee an potential POTUS!
