“Hello, hello, hello!” Biden told the excited crowd. “It’s a good night. It’s a good night. It seems to be getting even better. They don’t call it Super Tuesday for nothing. By the way, this is my little sister, Valerie, and I’m Jill’s husband. Oh no … You switched on me. This is my wife. This is my sister. They switched on me.” (RELATED: Biden Filmed Sniffing Baby On Super Tuesday In Viral Video)

Bolstered by the campaign withdrawals and subsequent endorsements of former South Bend, Indiana Mayor Pete Buttigieg and Minnesota Sen. Amy Klobuchar, the former vice president’s big night included wins in Virginia, Minnesota, Oklahoma, Tennessee, and an upset of Vermont Sen. Bernie Sanders in Kloubuchar’s home state of Minnesota.
