Thanks largely to her support for the war in Iraq, electoral support for Senator Maria Cantwell (D) has slipped once again—for the fifth survey in a row. In the latest Rasmussen Reports poll of an increasingly competitive U.S. Senate race, Senator Cantwell now leads former Safeco CEO Mike McGavick (R) 44% to 40%. She led by five points in May, eight in April, thirteen in March, fifteen in January.
