John McCain's advisor Carly Fiorina has weighed in on Tina Fey's Saturday Night Live impersonation of Sarah Palin.

"Well, I think that she looked a bit like her," Fiorina told MSNBC anchor Andrea Mitchell. (Watch above.)

She continued "of course, the portrait was very dismissive of the substance of Sarah Palin, and so in that sense, they were defining Hillary Clinton as very substantive, and Sarah Palin as totally superficial."

Fey returned to SNL on Saturday, where she and Amy Poehler who played Hillary Clinton delivered a special "non-partisan message" at the opening of the show's season premiere. (Watch the sketch.)

"Tonight we are crossing party lines to address the now very ugly role that sexism is playing in the campaign," Fey's Palin said.

"An issue which I am frankly surprised to hear people suddenly care about," Poehler's Clinton interjected.

After referencing Palin's famous joke about putting lipstick on a pit bull, Fey declared: "Just look at how far we've come. Hillary Clinton, who came so close to the White House. And me, Sarah Palin, who is even closer. Can you believe it, Hillary?"

Poehler responded: "I can not... It's supposed to be mine!

"I didn't want a woman to be President," Poehler continued. "I wanted to be president and I just happen to be a woman... I scratched and clawed through mud and barbed wire and you just glided in on a dog sled wearing your pageant sash and your Tina Fey glasses."

Compare celebs to the real people they play.

Fiorina said Fey was "sexist."

"Just because Sarah Palin has different views than Hillary Clinton does not mean that she lacks substance. She has a lot of substance," Fiorina told Mitchell.
