THE HILL: Team Clinton ‘worried’ about Bernie Sanders campaign.

Hillary Clinton’s campaign is “worried” about Bernie Sanders, whom a top Clinton aide described as a “serious force” in the 2016 battle.

“We are worried about him, sure. He will be a serious force for the campaign, and I don’t think that will diminish,” Clinton Communications Director Jennifer Palmieri said Monday in an interview with MSNBC’s “Morning Joe.”

“It’s to be expected that Sanders would do well in a Democratic primary, and he’s going to do well in Iowa in the Democratic caucus.”

Sanders, an independent senator from Vermont, has emerged as Clinton’s main foil in the Democratic primary.

While he’s still more than 40 percentage points behind Clinton in virtually all national polls, he’s greatly improved his stock in the early primary states.

I’d like to see the press ask him about his socialism, and how it differs from what’s been practiced in Greece.
