(Salem, OR) -- A new opinion poll on the Oregon governor's race shows GOP state Representative Dennis Richardson trailing Democratic incumbent John Kitzhaber by a margin of 45 percent to 41 percent. The telephone survey, commissioned by Richardson and conducted by pollster Bob Moore, questioned 500 likely voters and has a plus-or-minus four-percent margin of error. Earlier this month, a Survey USA poll commissioned by KATU-TV showed Kitzhaber with a 48-to-36 lead over Richardson.
