Former Sen. Mike Gravel of Alaska made fun of his fellow, younger Democrats who polled below him in a new 2020 poll.

In a tweet Friday, the 89-year-old offered his "condolences" to Sens. Kirsten Gillibrand, 52, and Amy Klobuchar, 59, and Reps. Eric Swalwell, 38, and Seth Moulton, 40. He also called them "fake progressives and stooges for corporate power."

Our condolences to @ericswalwell, @SenGillibrand, @sethmoulton, and @amyklobuchar (all fake progressives and stooges for corporate power) for polling below us in the new Harvard/Harris poll. There's always next time! — Sen. Mike Gravel (@MikeGravel) June 1, 2019

Gravel was referring to the latest Harvard CAPS/Harris Poll survey. It showed him receiving roughly 1% support in a question to Democrats about who they would support in the 2020 presidential primary.

The four individuals he mentioned got a couple votes, if any, and registered below 1%. Former Vice President Joe Biden led the poll with 36%, followed by Sen. Bernie Sanders at 17%.

Last week Gravel took a shot at Biden after the front-runner told a 10-year-old girl, "I’ll bet you’re as bright as you're good-looking," and taking her by the hand to present her to the press and standing behind her with his hands on her shoulders during a town hall event. "Not only is Joe Biden's creepiness around young girls not something to be dismissed lightly, his refusal to fully apologize and change his ways is indicative of how little he cares about sexual assault. We deserve a meaningful improvement over Donald Trump: Joe ain't it," Gravel tweeted.

Biden has faced repeated scrutiny over his habit of touching and getting very close to women and girls.

Gravel served as one of Alaska’s senators from 1969 to 1981 and gained notoriety for publicizing parts of the Pentagon Papers in the 1970s. He ran for president in 2008 but failed to gain traction. His campaign was known for an avant-garde campaign video with him staring into the camera before throwing a large rock into a pond. After not doing well with Democrats, Gravel switched to the Libertarian Party and unsuccessfully mounted a run for its nomination.

Gravel announced he was running for the 2020 Democratic nomination in April and released a campaign video titled “Rock 2.0."

Gravel, a long shot at best, told the Washington Examiner he is vying to qualify for the first Democratic debate in order to push his message of moving the party further to the left. He also said the current leadership of the Democratic Party is too closely associated with the Clinton family.

“Who’s in charge was put in place by the Clinton wing of the party, which is the conservative wing of the party, and it’s unfortunate that the Democratic Party has moved over to the right,” he said.

If he won, Gravel would be the oldest person to be elected president. Ronald Reagan was the oldest person to be elected at 73 when he won his second term in 1984.
