WHEN THEY GO LOW… Nancy Pelosi laughs as California Democrats chant ‘F*ck Donald Trump!’ raising 2 middle fingers.

The Calif. Rep. stood by, laughing, as the state’s Democrat Chairman John Burton raised two middle fingers as he encouraged the crowd at the state convention in Sacramento to chant “F**k Donald Trump.”

Democrat leaders at the convention used their time to deride President Donald Trump and beat the familiar drum of tying him to Russia, the Associated Press reported.

Sen. Kamala Harris told the crowd that the president is putting “Russia first, America second.”

“The world, literally the world, is counting on all of you, counting on California to reject Trump’s deception and destructiveness,” Gavin Newsom, the California Lieutenant Governor, said.

But it was Burton who took it to the classless extreme.

“All together now,” he told the crowd, encouraging them to chant as he raised his two middle fingers. “F**k Donald Trump.”

Daddy issues.
