Former DNC interim chair Donna Brazile is making a bold prediction for the 2020 presidential race.

In a conversation with MSNBC’s Chris Matthews she addressed potential Democratic contenders.

"I predict tonight that there will be literally over 25 people who will consider running for president. Perhaps Joe Biden, Bernie Sanders."

When pressed as to whether 75-year-old Biden or 76-year-old Sanders would be too old to run for president in an election that's still nearly three years away, Brazile said no.

"I think the Democratic Party should allow everybody to run, everybody who wants to run. Let's not dog people just because of their age."

Meet some of the Democrats who might challenge Trump:

Kirsten Gillibrand (D-NY) - Gillibrand has long been seen as potential presidential material, and her decision to vote against almost every one of Trump's Cabinet nominees has earned her renewed praise on the left. A recent profile in New York magazine further edged her toward the national stage. Photo By Bill Clark/CQ Roll Call Sen. Elizabeth Warren (D-MA) - In her new book, Warren reveals for the first time that she considered running in 2016, when liberals were begging her to enter the race. This year, Warren joined the Armed Services Committee, filling a major national security gap in her resume. First though, she'll have to win reelection next year in Massachusetts, where some Warren allies expect Republicans to spend heavily to defeat or at least damage her. REUTERS/Joshua Roberts Sen. Cory Booker (D-NJ) - Booker is a crowd favorite whenever he speaks to Democratic audiences and is expected to headline several party fundraising events this year. One of the few African-Americans in the Senate, Booker has a big social media following and is a darling of the Manhattan donor class. His precedent-breaking testimony against Attorney General Jeff Sessions was a high-profile event that endeared him to many on the left. REUTERS/Brian Snyder Sen. Bernie Sanders (I-VT) - Sanders won millions of votes during his unexpectedly strong presidential primary bid last year, which gave him a massive following and small-dollar donor base that's the envy of many Dems. He's the most popular politician in America, according to some surveys, and inspires enthusiastic loyalty. But Sanders would be 78 in 2020, and while his age doesn't seem to slow him down, Democrats may want a fresher face. REUTERS/Mary Schwalm Former Gov. Martin O'Malley (MD) - No one has shown more interest in 2020 so far than O'Malley, who has been traveling to key states to campaign for Democrats and who told NBC News in January that he "just might" run for president again. O'Malley failed to crack 1% in the Iowa caucuses last time around. But he was convinced there no room for anyone in a race so clearly defined by Hillary Clinton and Sanders, and insists that he could perform better under different circumstances.

"Never say never," Biden told "Late Show" host Stephen Colbert. "You don't know what's going to happen. I mean, hell Donald Trump's gonna be 74. I'll be 77 and in better shape. I mean, what the hell?" Photo by Brad Barket/WireImage Gov. Andrew Cuomo (NY) - Cuomo has built record of accomplishments in his time leading New York State, including the recent passage of a universal college tuition program, even though he's also racked up some detractors along the way. And unlike some of the other 2020 possibles, he's hardly shown a relish for taking on Trump. Photo by Brad Barket/WireImage Sen. Kamala Harris (D-CA) - The former California Attorney General just got to the Senate in January, but many party insiders think she's interested in higher office and that she would be a formidable candidate for the White House. Political talent scouts have been watching her for years, with a 2015 Washington Post headline asking, "Is Kamala Harris the next Barack Obama?"

At 70 years of age on his Inauguration Day, President Donald Trump became the oldest president to enter the Oval Office earlier this year.

Brazile said Biden and Sanders should be able to run if they can “reinvigorate” the party or bring fresh ideas to the table, then mentioning Hillary Clinton or Senator Elizabeth Warren could also run if they wanted.

Other rumored contenders for the 2020 race on the Cemocratic side include Senators Cory Booker of New Jersey, Kirsten Gillibrand of New York and Kamala Harris of California.
