Stumping for Bernie Sanders today in Wisconsin, actor Tim Robbins suggested that Hillary Clinton's delegate lead was a figment of the mainstream media and the Democratic establishment's imagination.

He said that her first big primary win, in South Carolina, was overblown.

'After the Southern primaries you had called the election – and who's fooling who?' Robbins said, according to video from ABC News. 'Winning South Carolina in the Democratic primary is about as significant as winning Guam – no Democrat is going to win South Carolina in the general election.'

'Why do these victories have so much significance?' he asked.

The actor, who most recently appeared on HBO's foreign policy comedy 'The Brink,' said he had come before a Green Bay audience to 'talk to our friends in the Democratic Party that feel Bernie in their hearts, but are supporting Hillary with their pragmatic brains,' at one point hinting those supporting the frontrunner were 'sheep.'

'These are not bad people,' Robbins said of those Democrats not feeling the Bern, according to video shot by the Green Bay Press-Gazette. He had to hush some low boos.

'They fear the Republicans' radical and dangerous divisiveness as much as we do,' Robbins added.

He suggested the problem was that Democrats have been fed 'a steady stream of simplistic propaganda that furthers the establishment's narrative.'

'That Hillary is the presumptive nominee,' he said was the line.

Robbins said it was the mainstream media that was peddling this fiction.

Currently Clinton is 263 delegates ahead.

'If we were sheep, if we had gotten in line, it would be no problem,' Robbins said of those Democrats supporting Sanders.

'The media and the ghosts of the DLC would have had their way and government would carry on as it has carried on for the past 30 years,' he continued, name-dropping the Democratic Leadership Council, the moderate group that formed in the 1980s and paved the way for President Bill Clinton's election.

In the past, Robbins noted how 'outsider candidates like Bernie Sanders would be marginalized and tolerated for a few primaries before falling in line with the Democratic party structure.'

'But the DNC and the Clintons have a big problem: Times have changed,' Robbins said.

'Bernie is not our [Howard] Dean,' he said, pointing to another Vermonter, the state's governor who ran an outsider bid in 2004.

'Bernie is not the obligatory progressive that will keep the left in line until the presumptive moderate nominee emerges,' Robbins said.

'Bernie is not the Democratic party insider that will bow down to the wishes of the elite of the party,' he continued.

'We are done with that patriarchy,' Robbins added.

The actor complimented Sanders for one of his biggest differences with Clinton – his vote on the Iraq war.

'There are moments in history where political pragmatism can lead to disaster,' he said of that particular decision, though suggested that Democrats supporting Clinton are doing it solely for pragmatism as well.

'I understand our friends' resistance to Bernie Sanders,' Robbins noted.
