Turnout was light today, Tuesday, for California’s state primary elections, mainly because the state had already held its presidential primary on Feb. 5. Waiting for voters at the Point Reyes Station polling place in the firehouse are election workers (from front): Doug Long, Cathleen Austin, and Cindy Knabe.

US Senator Barack Obama today clinched the Democratic presidential nomination, as numerous news organizations early this afternoon began projecting he would.

Acknowledging her opponent’s commanding lead in delegates to the nominating convention, Senator Hillary Clinton told Democratic politicos in New York that she is willing to be Obama’s running mate.

Senator Obama, 46, is the first black presidential nominee of a major US political party.

Obama was born in Honolulu to a Kenyan father and a white American mother, who met at the University of Hawaii. His parents soon separated, however, and eventually divorced. His mother’s second husband was Indonesian, and when he was six, Obama moved to Indonesia for four years. He then returned to Hawaii where he lived with his maternal grandparents while attending 5th through 12th grades.

Obama graduated from Columbia University where he majored in Political Science, specializing in International Relations. In 1991, he received a law degree magna cum laude from Harvard Law School.

From 1993 to 2004, Senator Obama taught Constitutional Law parttime at the University of Chicago Law School while also working as an attorney. He was elected to the Illinois State Senate in 1996 and the US Senate in 2004.

Meanwhile, this news blog at 10 a.m. today (which is when I got up) projected Supervisor Steve Kinsey and Congresswoman Lynn Woolsey would easily win their races.

Incumbent Kinsey (left) ran unopposed in the nonpartisan Marin County race for the Fourth District.

He will now serve his fourth term on the Board of Supervisors, representing all of West Marin, along with pieces of Larkspur, Corte Madera, and San Rafael.

Incumbent Woolsey (right), who represents Marin and Sonoma counties in the US House of Representatives, likewise ran unopposed in the Democratic primary.

In November, Woolsey will face Michael Halliwell, who was unopposed in today’s Sixth District Republican primary. Woolsey has already served eight terms in the House, where she has one of the most liberal voting records of any member.

Update on the State Senate Democratic Primary: With 43 percent of the vote, Assemblyman Mark Leno handily outdistanced Assemblyman Joe Nation (29.3 percent) and incumbent Carole Migden (27.7 percent) in the Third State Senate District.

The district includes Marin County and parts of San Francisco and Sonoma counties.

Leno (left) will face Republican Sashi McEntee in November’s general election. McEntee ran unopposed in today’s Republican primary.

The Third State Senate District, like Woolsey’s Sixth Congressional District, is overwhelmingly Democratic, and a victory in either Democratic primary is often tantamount to election.
