ABOUT THE DETROIT DEBATE

There will be 10 candidates each for Detroit's July 30 and July 31 debates, which are scheduled to run from 9-11 p.m. on CNN. On July 18 at 8 p.m., CNN plans to televise a live random drawing to decide which candidates will debate on which nights. 

A newcomer will take the Detroit debate stage later this month, joining 19 Democratic presidential candidates who debated in Miami, according to the list of participants released Wednesday by the Democratic National Committee. 

Montana Gov. Steve Bullock will make his first appearance in the second round of debates after U.S. Rep. Eric Swalwell of California, who participated in the June 28 Miami forum, dropped out of the race on July 7. Political experts said Bullock's improvement in fundraising and polling results, combined with Swalwell's dip in fundraising after the Miami debates, prompted the California Democrat's departure. 

There will be 10 candidates each for Detroit's July 30 and July 31 debates, which are scheduled to run from 9-11 p.m. on CNN. On July 18 at 8 p.m., CNN plans to televise a live random drawing to decide which candidates will debate on which nights. 

The two-hour forums will include opening and closing statements. The candidates get 60 seconds to respond to questions from moderators Jake Tapper, Don Lemon and Dana Bash, and 30 seconds for responses and rebuttals. Candidates attacked by name by another candidate get 30 seconds to respond.

But unlike the Miami debates — which were run by NBC, MSNBC and Telemundo — CNN doesn't plan any show-of-hands or one-word-response, down-the-line questions.

In an effort to discourage candidate interruptions that cropped up during the Miami forums, CNN plans to reduce the time of any candidate who consistently interrupts the answers of other candidates.

Here is information about the candidates, listed in alphabetical order, and those who didn't qualify for the televised forums at the Fox Theatre.
