I haven't seen any polls. In the meantime, I did look at Jerry Brown's contributors. He has Dianne Feinstein and her husband, Richard Blum, on his side. Also, the Tsakopoulos family (big Angelides supporters), Sherry Lansing, Steven Spielberg, Larry Ellison, GAP Chief Donald Fisher and wife (also big Arnie supporters), and several of the Unions. Brown has raised about $3.5 million to Delgadillos $2 million. 70% of Brown's donations are coming from Northern California (vs. Rocky's 6%) and 24% from Southern California (vs. Rocky's 84%).
This looks like a North vs. South fight.
That sounds somewhat similar to the Senate race battle in '92 for the open Cranston seat. However, in that case, you had 2 Northerners (Boxer, and Lt. Gov. Leo McCarthy) vs. 1 Southerner (L.A. Rep. Mel Levine). By all accounts, Levine should've been able to exploit the regional situation, but as the most "Conservative" (albeit still very liberal), he placed a paltry 3rd. The carryover to the general reflected Southern CA not wanting two Bay Area Northerners representing it in the Senate (Bruce Herschensohn carried Southern CA in the general, as did incumbent Sen. John Seymour from Anaheim against Feinstein).
It was interesting to read in Barone's '94 Almanac that he criticized Wilson for not appointing a little-known Stanford Professor named Condi Rice. ;-)
