The Clintons’ patience for Bernie Sanders are wearing thin — again.

During an appearance in Riverdale, New York for Hillary, Bill Clinton slammed Sanders and accused him of making a “sneering reference” to Hillary’s “mammoth victories” in the southern states.

“About the only thing that disappointed me about that debate last night was the sneering reference that her opponent made to the mammoth victories that she won in the south.”

Then, seeming to mimic Sanders, Clinton said sarcastically, “Oh, that’s just the south. We know how conservative they are.

“Well, excuse me, but Democrats need to win Florida and North Carolina to get elected and they are not and they are states of the future, highly diverse. And she won a big victory there.

“She won in Mississippi partly because they have a mayor in Jackson, an African-American guy, who is the embodiment of the future, who helped her.

“She won in Alabama — 93% of the African-American vote and a majority of the white vote.”

He said Hillary posed “as a racist mother” during her time working for the Children’s Defense Fund.
