San Francisco Chronicle, 24 Oct 2010 – No TV ads. No billboards. Just a lot of news conferences, endorsement announcements, mailings by special-interest groups and phone calls to voters. That’s what the battle has consisted of so far in the campaigns around the lowest-key, highest-interest election issue on the Nov. 2 ballot – Proposition 19, which would legalize personal marijuana use for adults. And that’s pretty much the game plan from here to the end.
