CNN will host the Democratic candidate debate, sanctioned by the California Democratic Party, Jan. 31, the week before Super Tuesday. Wolf Blitzer, who moderated a Democratic debate earlier this month, will act as moderator.
CNN will also host the final Republican candidate debate Jan. 30. The Republican debate will be held at the Ronald Reagan Presidential Library, which hosted the first Republican debate to feature all eight candidates in May on MSNBC.
Anderson Cooper, who moderated the CNN/YouTube Republican debate last week, will reprise his role for the final debate before Super Tuesday.
CNN's two November debates, the November 15 Democratic debate and the Republican YouTube debate, were the two most watched debates of the presidential primaries.
