We want one winner in Iowa, a different one in New Hampshire, yet another in South Carolina, and so forth.
We may get that-Warren wins Iowa, Sanders wins New Hampshire but it will probably still be Biden as nominee if he wins S Carolina-then Super Tuesday
the only way Biden gets knocked out is if he loses all 3
I think Trump has a better chance against Sanders or Warren,Biden still polls well with independents and gaffes will be ignored if he is the nominee
