(Portland, OR)  --  A new opinion poll on the Oregon governor's race shows incumbent Kate Brown and Republican challenger Bud Pierce are less than two points apart.  A telephone survey of 700 voters conducted by Clout Research shows Brown preferred by more than 43-percent, while Pierce comes in with 42-percent.  Clout Research pollster Fritz Wenzel says while his firm services mainly Republican clients, he wasn't commissioned to conduct this survey.  The poll shows that Pierce, who's a Salem oncologist, has the edge over Brown with independent voters.
