New York City Mayor Bill de Blasio, a surrogate for Senator Bernie Sanders, had some harsh words for Pete Buttigieg after his major loss in the Nevada caucuses.

De Blasio tweeted at Buttigieg directly telling him to “try not to be so smug when you just got your ass kicked.”

“And hey @PeteButtigieg, try to not be so smug when you just got your ass kicked. You know how we form a winning coalition to beat Trump? With a true multi-racial coalition of working Americans: something @BernieSanders has proven he can do + you haven’t. Dude, show some humility,” de Blasio tweeted.

The tweet had over 36,000 likes in less than two hours.

Following his loss, Buttigieg gave a speech warning against the party nominating Senator Sanders.

“Sen. Sanders, on the other hand, is ignoring, dismissing, or even attacking the very Democrats we absolutely must send to Capitol Hill in order to keep Nancy Pelosi as Speaker, in order to support judges who respect privacy and democracy, and in order to send Mitch McConnell into retirement. Let’s listen to what those voices are telling us,” Buttigieg said during his speech.

Buttigieg accused Sanders of promoting pie-in-the-sky ideological purity that would lead the party to lose in 2020.

“That is the choice before us: We can prioritize either ideological purity or inclusive victory. We can either call people names online or we can call them into our movement. We can either tighten a narrow and hardcore base or open the tent to a new, broad, big-hearted American coalition,” Buttigieg said.

Sanders is now expected to overtake Buttigieg in the delegate count.
