Not all Democrats gave Hillary love "out of the gate"

The Hillary 2016 campaign pot is officially brewing, but not every member of her party is ready to jump to the table. Some are still looking for Clinton to lay out specifics about her platform.

"The progressive wing of the party seems to be taking this posture which is that they want to call the tune a little bit with her and they're not willing to give their love right out of the gate," Bloomberg Politics Managing Editor John Heilemann said Monday on "CBS This Morning."

New York Gov. Andrew Cuomo was quick to voice his support, while New York City Mayor Bill de Blasio was more hesitant.

"We need to see the substance," de Blasio said Sunday on "Meet the Press."

"For him to take that posture, I think not only I was surprised, but apparently the Clinton people were furious," Heilemann said.

De Blasio is not alone.

Massachusetts Sen. Elizabeth Warren ducked questions Thursday on "CBS This Morning" as to whether she thought Clinton should represent the future of the Democratic Party.

One important question Clinton answered Sunday is why she's running: "Everyday Americans need a champion, and I want to be that champion," she said in her campaign video.

"It's an other-focused, 'we' focused roll-out, and that's been the thing that they've been trying to do," Heilemann said. "In this video, she's trying to say 'This is about voters and not about me.'"

Even with that platform, New York Times op-ed columnist David Brooks said creativity is key.

"The big question for me is the question of imagination; very undervalued political skill," Brooks said Monday on "CBS This Morning."

Clinton set off on the road for the first official events of her 2016 presidential campaign. Her announcement was no surprise, but many did not expect to find her traveling by "Scooby van" Monday morning.

Brooks attributed Clinton's "humility thing" to her desire to be relatable, but stressed, "everybody who wins combines old things in new ways."

"She somehow has to be fresh and offer something new as Obama did, as Bush did as Clinton did, something new, and she hasn't done that yet," Brooks said.

The video reflects a philosophy detailed in a memo sent to members of Clinton's team. Campaign manager Robby Mook outlined values to guide the campaign including, "We are humble."

"When you're humble, people usually say, 'Boy, he's humble.' You don't say it about yourself. So that's the challenge here," CBS News political director and newly-named anchor of "Face the Nation" John Dickerson said Monday on "CBS This Morning."

Heilemann pointed out another challenge.

"She is going to have a lot of support from African Americans, Latinos, those are constituencies that have always liked the Clintons a lot. But that new generation of voters - the thing Obama did so well, which was to get a new generation to vote for him in large numbers, she is untested there and she will need a lot of young support," Heilemann said.
