In an unusual twist, former state lawmaker and attorney John Carroll, who lost badly to former Gov. Linda Lingle in the Republican primary for U.S. Senate, on Friday endorsed U.S. Rep. Mazie Hirono, Lingle's Democratic rival. The conservative Carroll acknowledged that he disagrees with the liberal Hirono on most issues but praised her support for tourism and environmental protection. He described Hirono as a "candidate of character and sincerity."No On Lingle!
