Former Democratic National Committee interim chair Donna Brazile predicted a massive field of 2020 presidential candidates on Tuesday, telling MSNBC’s Chris Matthews she foresees 25 potential Democratic contenders.

Matthews asked Brazile about possible candidates like Sen. Bernie Sanders (I., Vt.) and Joe Biden, who are 76 and 75, respectively, and wondered if there should be an “outer age where you’re just too old to run” for presidents.

“Chris, I predict tonight that there will be literally over 25 people who will consider running for president,” she said. “Perhaps Joe Biden, Bernie Sanders.”

Other rumored contenders include Sens. Cory Booker (D., N.J.), Kirsten Gillibrand (D., N.Y.), Elizabeth Warren (D., Mass.), Kamala Harris (D., Calif.), Virginia Gov. Terry McAuliffe, Colorado Gov. John Hickenlooper, New York Gov. Andrew Cuomo and Los Angeles Mayor Eric Garcetti.
