The bipartisan Commission on Presidential Debates (CPD) held four debates for the 2012 U.S. presidential general election, slated for various locations around the United States in October 2012 – three of them involving the major party presidential nominees (later determined to be Democratic President Barack Obama from Illinois and former Republican Governor Mitt Romney of Massachusetts), and one involving the vice-presidential nominees (Vice President Joe Biden from Delaware and Congressman Paul Ryan of Wisconsin). The moderators for the debates were announced on August 13, 2012.
