“Don’t underestimate the power of the progressive nerve network,” said Suffolk University Political Research Center director David Paleologos. “It is alive, far reaching, and it is translating into political muscle in the New Hampshire Democratic primary.”
Writing Wednesday on NBC News' First Read, "Meet the Press" host Chuck Todd called Sanders' "faster-than-expected rise" the "biggest development in the presidential campaign so far this month."
Suffolk's poll includes a number of interesting data points:
Clinton has strong support in New Hampshire's most populated counties along the Massachusetts border, while Sanders is dominating — 47 to 26 percent — in the more sparsely populated counties in the north and west. Yep, the ones that border Vermont.
Women favor Clinton over Sanders by roughly 20 percentage points, but men are almost evenly split.
Perhaps most tellingly, among those who've actually heard of Sanders, Clinton is leading him just 38 to 35 percent. That's within the poll's 4.4 percent margin of error.
Thus far, Sanders' surge appears restricted to New Hampshire. Equivalent polls conducted by Morning Consult show Clinton leading him 54 to 12 percent in Iowa and 56 to 10 percent in South Carolina.
But Sanders has been drawing large crowds in both states. More than 700 people showed up to a rally in Des Moines last Friday, according to media reports. On Tuesday, the campaign announced it had shifted the location of a planned rally this weekend in Charleston, S.C., to accommodate the more than 1,000 people who had already RSVPed.
“The response in South Carolina has been tremendous,” field director Phil Fiermonte said in a statement.
And as Vermont Public Radio reported Tuesday, Sanders has raised more than $6 million so far, with the average contribution totaling less than $50. Campaign consultant Tad Devine has repeatedly said his boss hopes to raise $50 million to sustain his primary election campaign.
Not everyone is hyperventilating about Bernie.
Fivethirtyeight.com's Harry Enten, who wrote in April that Sanders "is almost certainly not going to be the Democratic nominee for president in 2016," is sticking to his guns. After the release of the latest Suffolk University and Morning Consult polls, he wrote, "If Sen. Bernie Sanders of Vermont wins the Democratic nomination, then everything we know about presidential primaries can be thrown out the window."
Enten's argument? Of the top five primary season frontrunners in modern polling history, all but eventual 2000 Democratic nominee Al Gore lost either the Iowa caucus or the New Hampshire primary. All five went on to win their party's nomination.
"[I]t’s important to keep in mind that even presidential steamrollers hit speed bumps and even — gasp! — lose states," he argued.
So how big a speed bump will Sanders turn out to be?
