Obama's Campaign Manager Talks Super Tuesday

The Democratic primary field is now down to five. Sanders, Biden, Bloomberg, Warren and Gabbard. The two most recent dropouts, Klobuchar and Buttigieg, stepped back after South Carolina to throw their support behind Biden, who is now the establishment standard-bearer for the moderate lane of the party. Polls have long showed Sanders leading in most of the Super Tuesday states, but Biden's strong showing in South Carolina appears to have moved the needle in his favor, particularly in Virginia, where he had trailed Sanders by five points, but now leads by 20 in the most recent polling.
