Hve been look for the number of registered voters in each catagory. Recent comments have said that alomst 100% of GOP are voting Brown, Indy are running 7:3 and as many as 20% of D are crossing over. Need the percentage of registered voters to do the math;
Formula .70(A) + 1(B) + .2 (C) should equal a good estimate of the final vote for Brown.
with A = percentag of Ind
B = percent of GOP
C = percentage of Rats.
