Ten presidential hopefuls will take the stage in Miami this week all looking to separate themselves from the pack of more than two dozen candidates battling for the Democratic nomination in 2020.

"If you're a lesser known candidate, you have to make some kind of mark in this debate. Because it will be a predicate for fundraising and media attention,” says Democratic pollster and strategist Brad Bannon.

Wednesday's participants include Senators Elizabeth Warren, Cory Booker and Amy Klobuchar, as well as New York City Mayor Bill de Blasio, Former Texas Congressman Beto O'Rourke and former HUD Secretary Julian Castro.

The candidates will all try to convince voters that they’re the one who should challenge President Trump in 2020, but each will have just 60 seconds to answer questions, and 30 seconds for follow ups.  

"The opportunity for a candidate to break through is pretty slim. You're not going to get a lot of time," says AP Washington Bureau Chief Julie Pace.
Senator Elizabeth Warren leads the polls among Wednesday’s debaters.  The Massachusetts lawmaker sees this as a chance to tell voters why she’s running.

“And the reason why I'm in this race is because we have a government right now that works great for billionaires and giant corporations, it's just not working for the rest of us and I think this is the chance to change that."

The 20 candidates who qualified were chosen to appear each night at random. Former Vice President Joe Biden along with Senators Bernie Sanders and Kamala Harris are among the more prominent candidates taking the stage Thursday night.

To qualify for the debate, candidates had to reach at least 1% in three separate polls, or receive donations from at least 65,000 different donors, with a minimum of 200 individual donors in no less than 20 states.

Massachusetts Congressman Seth Moulton, Montana Governor Steve Bullock, Mayor Wayne Messam of Miramar, Florida and former U.S. Senator Mike Gravel of Alaska did not qualify for the debates.

Meanwhile, on Wednesday, President Trump addressed this year's Faith and Freedom Coalition policy conference for the sixth time and his second as president. Trump calls it the largest faith-based get-out-the-vote group in the country.
