Although the presidential election is over a year away, potential and announced candidates have already appeared. This site from Project Vote Smart lists the candidates along with their biographies, key votes, speeches, ratings, and campaign finances. To keep up with their daily perambulations, go to the 2012 Daybook Calendar from Politico that is searchable by date, state, and candidate. And do not forget Reuters’ Factbox: Key dates in the U.S. presidential race, and C-SPAN’s Road to the White House should also be consulted for its video coverage of the candidates.
