Hillary Clinton was tired of her campaign being about nothing in June 2015 and wanted her campaign staff to come up with some real justification for her candidacy besides poll-tested lines and canned speeches, according to a 2015 email from Dan Schwerin, campaign director of speechwriting for Clinton.

The email correspondence is part of a series leaked online by WikiLeaks Monday.

“We just keep giving her poll-tested lines that don’t work, like make the middle class mean something.”

“HRC [Hillary Clinton] just called me and expressed a fair amount of frustration with how things are going,” Schwerin said in an email to a number of top Clinton aides. “She said we’ve given a series of very good policy speeches and in between we just keep giving her poll-tested lines that don’t work, like make the middle class mean something.”

Schwerin said Clinton liked the speech’s “Four Fights” metaphor.

According to The Daily Signal, the canned metaphor means building a fairer economy, strengthening families, maintaining world leadership, and reforming government.

But the poll-tested canned lines on other issues were getting in her way, Schwerin wrote.

Schwerin sent the email to Jennifer Palmieri, the communications director for the Clinton campaign, and John Podesta, the campaign chairman.

WikiLeaks has promised a steady stream of emails and other files in the weeks preceding Election Day.
