A new poll of likely Democratic voters released on Wednesday reaffirmed Sanders’ lead in the early-voting state of New Hampshire.

The Bloomberg/St Anselm poll showed Sanders with a five-point lead in New Hampshire. That very same poll, taken in February showed Hillary Clinton with a 41-point lead. But a lot has changed since them.

Sanders first pulled ahead of Clinton in August, when a Boston Herald/FPU poll put him ahead by seven points. Since then, he has been hard to catch. At one stage, Sanders polled 22 points ahead of Clinton, according to a CBS/YouGov poll.

This latest poll shows Sanders with a 86 per cent favorability rating, higher than any other Democratic candidate, and Joe Biden. Just six per cent of New Hampshire Democratic voters view Sanders unfavorably.
