In the crowded field of Democratic presidential candidates, Bernie Sanders might be the front-runner, Kamala Harris might come from a bigger state, and Beto O’Rourke might have his skateboard, but Elizabeth Warren is the master of policy.

Many political observers say Warren is dominating the policy debate, but there is little evidence that being the policy wonk is helping her dominate the race for the nomination.

Policies Proposed

Massachusetts Sen. Elizabeth Warren has long been known as a consumer advocate and a critic of big corporations. But she's not the only progressive seeking the right to challenge President Trump in 2020 who is highlighting economic inequality.

Vermont Sen. Bernie Sanders, for one, fired up the base with these issues in 2016, after Warren passed on a bid. But this time, she isn't sitting on the sidelines.

In the crowded field of Democrats running for president, Elizabeth Warren and Bernie Sanders have a lot in common. That means they’re fighting for the same voters, who could face a difficult choice.

Here’s some of what the two progressive senators have in common:

Vermont Sen. Bernie Sanders brought his campaign for the 2020 Democratic presidential nomination back to New Hampshire this weekend. Sanders, who won the 2016 New Hampshire presidential primary in a blowout, told voters they could make good on the promise of his longshot run four years ago.

The 2020 Democratic presidential primary will be similar to 2016 in at least one regard: Bernie Sanders is running for the nomination. But political observers say the electoral landscape has changed dramatically since Sanders’ last presidential bid, and not necessarily in ways that favor his latest candidacy.
