If you want a secure border, or believe immigrants should enter the United States legally, Bernie Sanders thinks you’re a racist.

Sanders has released a new web ad in which he accuses illegal immigration opponents of racism.

“We have 11 million undocumented people living in this country,” Sanders said in Des Moines, Iowa on Saturday. “I am profoundly disgusted by some of the demagoguery and some of the racism that has been addressed at those people.

“People can disagree about immigration reform, but racism and demagoguery on this issue in the year 2015 is unacceptable.”

He didn’t name names, though it very easily could have been Hillary Clinton’s campaign, which in 2008 perpetuated the idea that Barack Obama was not born in the United States.

The Telegraph reported in 2011:

In 2005, Mr Obama went to Washington as the junior US senator for Illinois. The rumours about him persisted, but seemingly failed to take hold among political insiders and voters alike.

It was not until April 2008, at the height of the intensely bitter Democratic presidential primary process, that the touch paper was properly lit.

An anonymous email circulated by supporters of Mrs Clinton, Mr Obama’s main rival for the party’s nomination, thrust a new allegation into the national spotlight — that he had not been born in Hawaii.

“Barack Obama’s mother was living in Kenya with his Arab-African father late in her pregnancy,” it said. “She was not allowed to travel by plane then, so Barack Obama was born there and his mother then took him to Hawaii to register his birth.”
