Donald Trump will be standing at center stage when the 11 candidates face off at the CNN-sponsored debate at the Reagan Presidential Library in Simi Valley, California.

The lineup is the same as last month's opening debate, with one notable addition: former Hewlett-Packard chief executive Carly Fiorina, the only woman in the GOP field.

It's believed to be the largest debate field in modern political history, underscoring just how jumbled the fight for the Republican nomination remains with five months to go before the Iowa caucuses.

Chronicle writers Carla Marinucci and Debra J. Saudners, along with PolitiFact bring you live coverage of the debate:
