Judy Woodruff moderates two live debates among the major parties' presidential candidates. The first forum, featuring Democratic presidential candidates, will be presented live from the Adler Theater in Davenport, Iowa, on Thursday, September 20, 8:00-9:30 p.m. ET on PBS. Both debates will take place in Iowa - a critical stop for the presidential campaigns, since the Iowa caucuses are expected to be the first state contests of the 2008 primary season. The debates focus on health care and financial security. The second forum, featuring Republican presidential candidates, will be presented live from the Orpheum Theater in Sioux City, Iowa, on Thursday, October 25, 8:00-9:30 p.m. ET on PBS.
