Mayor Bill de Blasio had a no-sweat reaction Tuesday to the onslaught of late-night roasts over his presidential bid.

The 2020 Democratic long shot was greeted on CNN’s “New Day” with footage from comedians Jimmy Fallon and Stephen Colbert, who cracked jokes at his expense on their respective shows last week.

“That’s what they do for a living, it’s normal,” de Blasio told co-host Alisyn Camerota.

“You didn’t think there was something a little bit nastier about the reaction to your announcement?” she asked before pulling out a copy of The Post from last week laughing off Hizzoner’s quixotic run.
