Young Turks host: Warren should drop out, back Sanders

The Young Turks' host John Iadarola said Tuesday that Sen. Elizabeth WarrenElizabeth WarrenDimon: Wealth tax 'almost impossible to do' CNN's Don Lemon: 'Blow up the entire system' remark taken out of context Democrats shoot down talk of expanding Supreme Court MORE (D-Mass.) has no clear path towards the Democratic presidential nomination.

"The two paths that she potentially sees to winning do not actually exist," Iadarola told Hill.TV. "There is no electoral path, she's potentially not going to win a single state, including [Massachusetts]."

To clinch the Democratic presidential nomination, a candidate must have 1,991 pledged delegates. Doing well in California, which boasts 415 pledged delegates, would help any of the candidates get closer to that number.
