The DNC-sanctioned debate takes place at Miami Dade Community College, which is the nation's "largest campus-based institution of higher learning and the most diverse."

The Washington Post and Univision teamed up to host the debate. It will be moderated by Univision's Maria Elena Salinas and Jorge Ramos and Karen Tumulty of the Post.  Interestingly, in Sunday's debate, CNN generously gave live updates online, so expect it to happen again on Wednesday. 

The debate occurs six days before Florida's primary on March 15, where 214 delegates will choose their presidential bet.

As for the result of debate in Flint, Michigan, Time published who won the seventh Democratic debate. In an online poll, where 75, 263 online supporters participated, 87 percent backs Sanders, while 13 percent supports Clinton. Take note that this online count does not represent the eligible primary voters. The figure is based on online supporters and social media users.

For Sanders, he needs game changing-strategy to win the Democratic nomination, according to the Economist.  Despite winning the Maine, Kansas and Nebraska caucuses, the Vermont senator is badly lagging behind Clinton in the delegate count.  The senator has strong impact on young voters and white liberals--who dominated the Democratic voters in those three states. However, he has little support from the non-whites who matter much more in others states.

In order to get more support from Democratic voters, Sanders and Clint had some sharp exchanges in the recent Michigan debate.

Sanders criticized the legacy of Clinton's husband, particularly the negative effect of his criminal-justice and welfare reforms on blacks. Political analysts say the senator particularly picked these issues to have an appeal to black voters.

On the other hand, Clinton attacked Sanders on his mixed record on supporting gun controls.  She also defended Bill Clinton's legacy. She stressed that the median African-American wage increased by 33 percent in the 1990s.
