Former Secretary of State Hillary Clinton and Vermont Sen. Bernie Sanders will meet again Thursday night for the PBS NewsHour Democratic primary debate in Milwaukee. It will be the first debate since, well, last week, but primary season is in full throttle and plenty changes — especially in such a tight race.

The debate is set to be hosted at the University of Wisconsin-Milwaukee and will be broadcast at 9 p.m. EST on PBS and streamed live on NewsHour's website. The network said there will not be a pay wall to access the live stream on its website. To view the live stream, click here or watch it below.

PBS NewsHour anchors Gwen Ifill and Judy Woodruff will moderate the sixth Democratic debate. "As the nightly news broadcast on the nation’s public broadcasting system, the PBS NewsHour is a natural place for candidates vying for the American presidency to debate on the most important issues facing our country," said Sara Just, PBS NewsHour executive producer, in a statement.

"Gwen Ifill and Judy Woodruff are two of the best and most experienced journalists in the business; together they have covered some 15 presidential elections. Combined with the NewsHour’s deep bench of political reporters and producers, we are confident this will be a fascinating debate. More details to come soon!”

The debate will be the last chance for the candidates to duke it out before the first test of the primary race held below the Mason-Dixon line. Clinton and Sanders will need to woo voters in South Carolina and Nevada, where they are scheduled to head next week for the two respective primaries.

Nevada and South Carolina are the third and fourth states, respectively, on the Democratic primary presidential calendar, and have a more diverse electorate than Iowa and New Hampshire. Hispanics represent around 28 percent of Nevada's population, and constituents in South Carolina are 56 percent black. Both will prove to be crucial voting blocs in the 2016 election.
