Sanders may be on the verge of another New Hampshire win. Democrats aren't ready to get behind him.

Bernie Sanders has been running for president a very long time. Long enough to get nostalgic.

“Four years ago, I came to New Hampshire and I had a series of proposals that the political establishment said was very radical, too extreme,” Sanders told a crowd at Franklin Pierce University on Monday.

Many in the crowd hadn’t lived in the state back then. Many more had been too young to vote. They cheered along, applauding at the end of every sentence, as Sanders told them how he would overthrow the political order. The senator from Vermont was possibly on the verge of doing something moderate Democrats had been unable to prevent: winning the New Hampshire primary.

In the contest’s final hours, Sanders has minimized his own criticism of the party, pitching his campaign as a chance for the state to get things right and pick an electable candidate who will supercharge voter enthusiasm.

His Monday evening concert in Durham, Sanders said, would probably bring out the “largest turnout in the Democratic primary process.” His volunteers had knocked on one-fifth of all the doors in New Hampshire, sometimes putting a golf ball in a gloved hand, to make sure that people at home were listening.

But Sanders had already won New Hampshire once, by a 21-point landslide. Unlikely to beat him here, rival candidates and skeptical voters are still asking whether Sanders and his movement could be trusted to win a general election.

“He’s probably too progressive for me,” said Jacob Kirk, 59, who said had voted for Sanders in the 2016 primary and then cast another “anybody-but-Hillary” vote for Donald Trump.
