Libertarian Party
Four third-party U.S. presidential election candidates—representing the Libertarian, Green, Constitution, and Justice parties, who were excluded from the high-profile televised encounters between Mitt Romney or Barack Obama—attend their own presidential debate hosted in Chicago by the Free and Equal Elections Foundation, which hopes for a more transparent and open electoral system. Romney (with the Republican Party) and Obama (with the Democratic Party) refuse invitations to attend the debate, televised on international news channels but on no major U.S. network.
