Super Tuesday is one week away and Democratic presidential hopefuls are out campaigning in full force. Hamline University political analyst David Schultz says Super Tuesday is a critical day:

“It really tests all the candidates in a variety of ways including Senator Klobuchar. What Super Tuesday does coming right after South Carolina is really making it difficult for candidates to decide which of all the states to campaign in.”

More than a third of all delegates for the Democratic National Convention are up for grabs on Super Tuesday.
