We also did a survey on possible primary and general elections through Merriman River Group (March 2011; 1,012 registered voters statewide; 3% margin of error). I retained very good overall name recognition and favorability, prevailed in the Democratic primary matchups (for example, Case 47%, Hannemann 35%, Unsure 18%), and did best among the Democrats in a general election against presumed Republican nominee Linda Lingle (Case 49%, Lingle 37%, Unsure 14%).
