And then there were two: Biden surge forces out Democratic primary rivals

“A big effing case” is the way an expert put it, borrowing from one of Joe Biden’s most famous lines. Former Barack Obama vice president won the lion’s share of the Super Tuesday primaries and Bernie Sanders, a leader, won the US president’s Democratic nomination. The race is far from over, with almost two thirds of the delegates still to win. Have the moderates merged for good around Biden and does he have the right things to face Donald Trump in the fall?

Consolation for Sanders comes from California, the largest state in the United States. Enough to stabilize the ship? This again raises the question of how far left voters want to go while choosing a president. And will his supporters be aligned if the Democratic Socialist senator from Vermont fails?

Unlike the Republican Party, which is more or less indebted to the man who sits in the White House, Democrats must worry about compromises around a candidate and a platform that can bring together moderates and progressives . And what Tuesday’s high turnout shows is that whoever gets the nod is all that fits Trump.
