Barack Obama’s coalition of voters is not coming out to support Hillary Clinton.

Former Obama strategist David Plouffe had few answers for the grim reality that Clinton is lagging with Millennial voters, a key coalition piece to Obama’s electoral success.

After being told on Monday’s “With All Due Respect” that Clinton is 20 points behind Obama’s 60% support among young voters, Plouffe said, “That’s a problem, not just a campaign problem, that’s a problem.”

Plouffe believes the debates will help because it will provide “energy” to volunteers.

“The best way to get a Millennial — and listen, there’s a bunch of 18, 19, 20 year olds that didn’t vote for Barack Obama because they weren’t eligible. You’ve got to have a human being talk to them.

“They’re not just going to do it because they see an ad,” Plouffe puffed.

He acknowledged a lot of Millennials are choosing Libertarian candidate Gary Johnson, “and they’ve got to peel those off.”

“It’s not a crisis,” Plouffe claimed, “but it’s a huge problem.”

Adding to Clinton’s woes is new polling showing a closer than expected race in Massachusetts.

WBZ reports:

The bad news – her 13-point margin in our poll is surprisingly weak given the state’s deep-blue status and past voting history.

Barack Obama carried Massachusetts by a 23-point margin in 2012, and a 25-point spread in 2008. Clinton’s husband Bill won here in 1996 by 33-percent.

What’s weighing Clinton down?

It’s the same story as elsewhere across the country.

Her favorability ratings are way underwater, with 41-percent saying they’re very or somewhat favorable toward her, while 56-percent are very or somewhat unfavorable. It’s even worse for Trump, with a 31-66 percent split. But the most telling comparison is with President Obama, seen very or somewhat favorably by 51-percent of likely Massachusetts voters, unfavorably by 46-percent.

“It’s shocking, just shocking,” WBZ-UMass Poll Associate Director Tatishe Nteta tells the news station.

“The expectation was that she would destroy Trump in Massachusetts, but the fact that he is within shouting distance indicates that she has a real problem here.”
