Brown to announce for Calif. gov. Tuesday

California Attorney General Jerry Brown (D) is expected to mark the official launch of his gubernatorial campaign with a web announcement at 11 a.m. Pacific Tuesday.

The 71-year-old Brown, who served two terms as governor starting in 1975, has no public events set for his first day in the race. He's not expected to face a serious opponent in the Democratic primary.

Web announcements are becoming the norm for a candidate rollout. On Monday, Arkansas Lt. Gov. Bill Halter (D) announced his primary challenge to Sen. Blanche Lincoln (D) via an online video. Halter waited until Tuesday to begin a round of press interviews.
