Scarlett Johansson was not the only star supporting the presidential candidates. Fellow actor Chuck Norris backed Republican Mike Huckabee, while the blonde stunner attended Democrat Barack Obama’s rally in Coralville, Iowa, last week. An onlooker told People, “She [Scarlett] actually seemed a little shy when she first started speaking,” “But [she] warmed up to the crowd, who were eager to ask questions… It was pretty exciting and inspiration to see someone as big as her come and talk to her peers.”
