It's about numbers of votes and how to get them.

10. Yes, they have to be invested, but they don't have to be traded for campaign donations.

Let me quote the language from his wiki again:

When he campaigned for State Treasurer during 1974, the post was considered insignificant. Unruh's radio advertisements assured voters, "Make no mistake about it, I really want this job". Once elected, Unruh politicized the office. The Wall Street Journal noted he became "the most politically powerful public finance officer outside the U.S. Treasury". California pension funds were a major source of revenue for Wall Street underwriting companies, and Unruh secured campaign contributions in exchange for doing business with them. The New York Times said he had gained control of "an obscure post whose duties had long emphasized bookkeeping. In characteristic fashion, he soon transformed the job into a source of financial and political power that reached from California to Wall Street."

Also, you did not address anything in my reply 7 to you, only the P.S. reply (#8) about Unruh.

Forgive me, but making money in politics today about about one long California state politician who was in elective offices from September 1961 to January 1987 just is not persuasive or even particularly relevant. The DLC was not even incorporated until 1987 and that changed the Democratic Party and US politics dramatically, including on money issues.
