“Hillary has been a champion in the progressive arena my entire adult life,” “The West Wing” star said. "She has been at the forefront of protecting our most vulnerable citizens [by] fighting for healthcare.

“I think she’s the most prepared person by far, and I support her enthusiastically,” added Whitford, who portrayed White House Deputy Chief of Staff Josh Lyman on the political drama.

“In Wisconsin, I don’t think a lot of people understand that Hillary out-Bernied Bernie her entire life in terms of pushing the progressive agenda,” said Whitford, a Badger State native.

“Idealism is more than just talking about it,” he added. "Idealism is knowing what you can actually get done and getting it done.”

Whitford also dismissed claims that Democratic voters are unenthusiastic about Clinton’s campaign.

“I think it’s very easy on the left to fall in love with someone who doesn’t have perhaps as dirty a uniform [or] has been as battle-tested as Hilary has,” he said.

Whitford added that President Jed Bartlet, the Democratic chief executive on “The West Wing,” would readily vote for Clinton.

“There’s no doubt in my mind that Hillary would be President Bartlet’s choice,” he said of the character portrayed by actor Martin Sheen. "Nobody is more prepared to take that position on day one."
