What's happened to Warren, Biden? Dismal showings and questions about the future.

MANCHESTER, N.H — Joe Biden's and Elizabeth Warren's poor finishes in New Hampshire raise daunting questions about the future of their campaigns after both former front-runners were denied podium positions by a late-surging Amy Klobuchar.

Biden appears set to finish fifth and Warren fourth — a stunning result for two candidates who were neck and neck for national front-runner status as recently as October — and NBC News projected Tuesday that neither of them would meet the threshold to collect any delegates.

Klobuchar impressed at the last debate and a widely covered dinner in Manchester in the last few days ahead of the primary. NBC News exit polls showed that nearly half of voters said they made up their minds in the final days, a significant increase from previous years.
