So, after meeting wih Roos and resolving whatever points of contention were drawing Takei into the Primary race, Takei did, indeed withdraw from the 1980 California State Assembly race. (I don't know how much, if at all, Mr. Takei's then-closeted sexual orentation played a factor in his withdrawl from the race. I take him at his word that a solution to the "equal time" problem that would have caused his fellow Trek family to lose out on their residuals was the motivating factor for his withdrawl.)
I was living in Los Angeles at the time, and the details of your post was the general, accepted story of Takei's exit.
Very interesting times going into the 1980s.
Thanks for posting everything!
