Making her first solo appearance on the stump, Chelsea Clinton late Tuesday ripped Sanders over his proposals on healthcare and college affordability, arguing the White House hopeful wants to “dismantle” ObamaCare and Medicare.

Democrats have almost universally panned the attack, believing it to be ineffective and a misuse of her talents.

They note that Chelsea Clinton has mostly been used to highlight Hillary Clinton’s softer side as a mother and grandmother and say she seemed uncomfortable shedding her first daughter persona for the role of attack dog.

“The thing that tells you as much as anything about [the Clinton campaign’s] current state of mind is Chelsea going on the attack. It tells you everything you need to know,” said one Democratic strategist. “That this [challenge from Sanders] is real and they’ve got to be freaking out.”…

“I perhaps could see it coming from Bill, but I was taken aback hearing it from Chelsea,” said Grijalva, who backed President Obama over Hillary Clinton in 2008 after first endorsing John Edwards.
