Bernie Sanders is 'doing very well': Trump

Bernie Sanders strengthened his front-runner status in the race for the Democratic nomination with a narrow win in New Hampshire, dealing a setback to moderate Joe Biden as attention shifts to the next contests in the state-by-state process.

Pete Buttigieg, the moderate former mayor of South Bend, Indiana, built on his momentum with a close second-place finish after splitting much of the centrist vote with Senator Amy Klobuchar, who placed third after surging over the past few days.
