After polls closed in the first couple states, Hillary Clinton had taken Georgia, Virginia, Tennessee, Texas, Alabama, Arkansas and Massachusetts while Bernie Sanders claimed his home state of Vermont, Oklahoma, Colorado and Minnesota.
Democrats will vote in 11 states and American Samoa, with 865 delegates up for grabs. Delegates will be awarded proportionally on Super Tuesday; there are no winner-take-all states.
If Clinton takes a majority of the delegates on Super Tuesday, her campaign thinks it could build a lead large enough to put the race out of Sanders’ reach.
Should Clinton roll up such margins in the swath of Southern states that vote on Tuesday, it may not matter if she ekes out wins or close second-place finishes to Sanders elsewhere. Those wins may be enough to grow her delegate lead to the point where Sanders can’t catch up.
If he avoids blowout losses in Southern states — such as Alabama, Arkansas, Georgia, Tennessee and Texas — Sanders may be able to survive to see the calendar improve in his favor later next month.
With so many races going on, we wanted to make things easier to follow. You can return to this page during and after Super Tuesday to see a live state-by-state breakdown of how each candidate fared and any updated news.
We included a delegate tracker at the top that shows how close each presidential hopeful is to locking up the nomination. You can see how each state voted below.
We also created a separate page for the Republicans on Super Tuesday. It can be found here.
