Joe Biden is almost certainly on the precipice of announcing a 2020 presidential run, and this “slip-up” when educating the “new left” about his progressive credentials confirms it.

Oops … or maybe not oops.

Is he or isn't he?

But ol’ Joe could be just testing the waters.

Uh, so Biden just slipped and said he has the most progressive record of anyone who IS running. Crowd goes nuts, he quickly amends: "who would run." — Henry J. Gomez (@HenryJGomez) March 16, 2019

There is probably a reason many in the “new left” don’t know about Biden’s progressivism.

At any rate, it sure looks like the guy is running, which will be to the dismay of the other candidates who are all trailing him in the polls.

Iowa voter stands: "I love Joe Biden. I think he’s served this country well. But I want youth…I hope he doesn’t get in." Beto O’Rourke: “I have to disagree a bit. I think if Vice President Biden gets into the race, I think we could use his perspective." — Matt Viser (@mviser) March 16, 2019

They’d sure like to use his poll numbers if he doesn’t enter the race.
