Why Green Party Presidential Candidate Jill Stein Doesn't Want Either Clinton or Trump in the White House Jill Stein says she wouldn't be happy with either mainstream party candidate.

 -- Jill Stein, the presidential candidate for the Green Party, says she would be unhappy with either mainstream party candidate -- Hillary Clinton or Donald Trump -- in the White House.

“No doubt, I will feel really terrible if Donald Trump becomes president. But I will also feel really terrible if Hillary Clinton becomes president,” Stein told ABC News Political Director Rick Klein and Deputy Political Director Shushannah Walshe on this week’s “Powerhouse Politics” podcast.

“Because, unfortunately, many of the really scary things Donald Trump talks about, Hillary Clinton in fact has already done,” Stein added, referring to Clinton’s positions on Libya and affairs in the Middle East.

Stein credited Vermont Sen. Bernie Sanders with striking a chord among American voters who are distressed with the status quo.

“There’s no way we would have gotten here if it hadn’t been for the work of Bernie Sanders and his campaign to really build the momentum,” Stein said, “and I think really lift the curtain on how very strong this movement is for deep change across America.”

Stein said that Sanders supporters should not pack up their bags and settle for a candidate with whom they are unhappy. “The struggle goes on,” Stein said, appealing to Sanders voters.

“And after all the wonderful work that they have done lifting up this fight for economic justice and equality, and an economy that works for everyday people and workers, that there’s no need to send it back to the graveyard of the Democratic party,” Stein said, referring to the work of the Sanders campaign.

“Because at the end of the day, we’ve seen, it’s very hard to have a revolutionary campaign inside of a counter-revolutionary party,” Stein added, discussing Clinton’s out-performance of Sanders among Democratic Party members.

Stein also discussed the likelihood that she would be unable to debate Clinton and Trump on a debate stage, due to rules established by the Commission on Presidential Debates.

The commission is a “private corporation, run by the Democratic and Republican Parties,” Stein said. “If a candidate is on enough ballots that they could actually win the election and they are a realistic and credible choice for being on the ballot for the majority of voters, then voters deserve to know about that candidate.”
