There's only have about a quarter of the delegates at stake today that they did two weeks ago, but it's an important date as it could make or break the two left in the race. Today will be the first one-on-one matchup between Sanders and Biden.
Primaries are being held in 6 states, including MO, ND, MS, ID, WA, and MI. Michigan in particular will be interesting as it will be a testing ground in a state that's likely to be a key battleground this November. Sanders won the state in 2016, so it's hard to imagine him catching Biden unless he wins there.
If you're a poll watcher, Biden is way ahead, with a 16 point lead nation wide, including whopping 22 points in MI, the largest state on today's slate, and 30 points in MO. Even WA, which was thought to be a Sanders stronghold, is a virtual toss-up. Mississippi is likely to break Biden's way as well.
Biden has been picking up a steady stream of endorsements, the latest being former POTUS candidate Sen. Cory Booker. If Biden wins the day today, the race could be all but over.
