Democrats running for president will need to decide which one they're supporting or risk ending up in the muddled situation Sen. Kamala Harris, D-Calif., found herself in last weekend.

Bernie Sanders, I-Vt., that would effectively replace existing private health insurance plans with a souped-up version of Medicare that covers more than the current program and requires no premiums or deductibles.
