WASHINGTON (AP) — The Associated Press was able to declare President Joe Biden the winner of a near clean sweep of Democratic Super Tuesday contents based largely on initial vote results that showed him winning about nine out of every 10 votes in almost every contest. The lone exception was American Samoa, where the local Democratic Party announced it had awarded most of its delegates to a little-known candidate. Biden has now won 19 out of 20 contests and has more than quadrupled his total number of delegates. He is on track to win enough delegates to clinch the nomination by March 19.
