Cedar Falls Tea Party leader Judd Saul places copies of the Constitution on chairs in his parent's backyard as they prepare to host Republican presidential hopeful Rick Santorum (R-PA) just west of Independence in Cedar Falls, Iowa, July 6, 2011. Every four years, candidates criss-cross the small state to appear before voters who understand -- and take seriously -- the role Iowa's first-in-the-nation caucuses play in narrowing the presidential field for the rest of the country. So the hopefuls present themselves before everyday Iowans in diners, businesses, public auditoriums and private homes to present their policies and positions and to be grilled on them. Voters in the Iowa caucus and the New Hampshire primary will be the first to cast ballots in the upcoming U.S. Presidential race. REUTERS/Jessica Rinaldi (UNITED STATES - Tags: POLITICS SOCIETY)
