Hillary Clinton is not yet a candidate for president, but she just can’t help but attack a surging one.

The failed 2016 Democrat nominee once again took the opportunity to attack Bernie Sanders just hours before the Iowa caucuses.

Fox News today aired a clip of Clinton’s interview on “Your Primary Playlist” with Joy Reid.

“What do you think that he can do — whether he’s the nominee or not the nominee — to help get to that point of unifying people against Trump?” Reid asked.

“Well, he can do it, for one,” an incredulous Clinton responded. That’s not our experience from 2016.

“There was no question about who was going to be the nominee,” she continued, having noted previously that she received millions more votes than the socialist did.

“But, unfortunately, you know, his campaign and his principal supporters were just very difficult and really, constantly not just attacking me, but my supporters,” Clinton said.

“It had an impact.”

The relationship remains raw, as evidenced by Rep. Rashida Tlaib encouraging a Sanders audience to boo Clinton.
