Many potential candidates have sought to stand out from the field through vocal opposition to the Trump agenda — voting against the bipartisan two-year budget deal or calling for the president’s resignation.

Sanders reportedly met with top advisers in late January to discuss a potential 2020 run. But Sanders said he’s focused on his reelection in 2018. Still, the 2016 Democratic primary candidate hasn’t shied away from opportunities to contrast himself to Trump. The favorite of the Democrats’ progressive wing delivered his own response to the State of the Union address, calling Trump a “bully.” If elected, Sanders would be 79 when taking office in 2021.

Warren, who will be 71 on Inauguration Day in 2021, was one of several Senate Democrats with possible presidential ambitions who voted against the two-year budget deal.

Buttigieg, 36, has kept busy since making a headline-grabbing bid to chair the DNC.
