Green Party presidential nominee Jill Stein is warning liberal progressives not to throw away their vote by supporting corporatist Democratic nominee Hillary Clinton.

“Don’t waste your vote on corporate Democrats. #InvestYourVote,” Stein wrote on Twitter on Wednesday:

If Trump's campaign is flailing, does a "spoiler" vote even exist anymore? Don't waste your vote on corporate Democrats. #InvestYourVote — Dr. Jill Stein🌻 (@DrJillStein) October 12, 2016

Stein then retweeted a statement from the Green Party’s official Twitter account which read, “It’s time to #InvestYourVote in building a people’s party – not waste your vote on corporate party candidates that continue to betray you.”

“Unlike the Democrats and Republicans, we don’t cuddle up to Wall Street and special interests with our ‘public’ and ‘private’ positions,” Stein added in a separate tweet, referring to the recent WikiLeaks revelation that Hillary Clinton said that politicians need to have “both a public and private position” on every issue:

Stein observed that “corporations were originally chartered to serve the public good, but they’ve become monsters that dominate our government.”

Stein has previously explained that the liberal progressive agenda–on health care, crime, climate change, trade, etc.– cannot be accomplished under a corporatist like Hillary Clinton. Stein argued that a Clinton presidency will simply be the continuation of the policies supported by Washington’s “uniparty,” which is controlled by special interest donors–and will not in any way advance the goals of liberal progressives.

Seeming to borrow Trump’s moniker for Clinton, Stein also attacked DNC chair Donna Brazile for her “crooked” behavior– providing Clinton’s campaign with a question in advance for a town hall as Clinton was trying to defeat Bernie Sanders in the Democratic primary:

Invest your vote in a movement party, not in more crooked behavior from the Democrats! PodestaEmails4 https://t.co/oST6YiMYmu — Dr. Jill Stein🌻 (@DrJillStein) October 12, 2016

Stein is a Harvard Medical School graduate, a mother to two sons, and a practicing physician, who became an environmental-health activist and organizer in the late 1990s. As the Green Party’s 2012 presidential candidate, Stein holds the record for the most votes ever received by a female candidate for president in a general election.

While third party Libertarian nominee Gary Johnson has received quite a bit of media attention throughout this election, Stein said that she has experienced a virtual media blackout. Stein urged supporters to help her “#BreakTheBlackout from corporate media.”

Stein suggested that the reason for the media blackout stems is because she is an effective messenger against Washington’s “uniparty.”

“I debated @MittRomney in 2002 and was declared the winner by viewers. After that they locked me out of the debates,” Stein tweeted. “The Democratic and Republican candidates + @GovGaryJohnson refuse to debate me because they’re scared. #OccupyTheDebate”:
