Can some one tell me the party sizes in Washington? I mean for Rossi to have 90% of GOP compared to Gregoire's 87% of Dems and for Rossi to have a 13 point lead among Independents I would think he would lead unless the Dems have a huge registration edge.
We don't have party registration.
SurveyUSA tends to lowball independents, but going by their last poll:
Democrats (39%)
Republicans (27%)
Independents (26%)
Giving Rossi 90-7 among Republicans, Gregoire 87-10 among Democrats, and Rossi 53-40 among independents (rough estimate with D+R+I):
Gregoire: (0.39*0.87)+(0.27*0.07)+(0.26*0.4) = 46.22%
Rossi: (0.39*0.1)+(0.27*0.9)+(0.26*0.53) = 41.98%
Margin: Gregoire +4.24%
So, yeah, perfectly in line with what we've been seeing.
