Congressman Joe Kennedy III gave the Democratic response to the State of the Union — and drew comments both about his policy ideas and for what was dripping off his lips.

The 37-year-old Kennedy family scion — who is the grandson of RFK — appeared to have large, bizarre wet spots at the corners of his mouth as he talked after President Trump’s speech, prompting people to wonder if it was drool or an abundance of Chapstick.

“Marco Rubio had dry-mouth during his #SOTU response in 2013. Joe Kennedy has drool-mouth,” tweeted GOP pollster Frank Luntz, as he compared Kennedy’s speech to the disastrous 2013 Republican response by Sen. Marco Rubio (R-Florida) in which he awkwardly reached for water.

Kennedy, a Massachusetts Democrat, passionately advocated for America’s working class before a Ford Mustang in a school auto shop and even appealed to Latino voters by speaking Spanish.

But it was talk of his wet mouth that dominated the Twitter response to the Dem response.

“And all we’ll remember is the drool on his face,” GOP operative Josh Holmes tweeted.

“Rubio had his water. Kennedy has his drool,” according to American Conservative Union chairman Matt Schlapp.

Despite Kennedy’s not-ready-for-prime-time embarrassment Tuesday night, Luntz predicted it won’t water down the Democrat’s career.

“Of course, Marco Rubio bounced back and so will Joe Kennedy,” Luntz tweeted.
