A.M. Splash: Polling on Tax, Term-Limit Measures; Memorial Day Weekend Congestion; BART Proposing Weekend Bus Service

...The Public Policy Institute of California survey, conducted last week, found a sharp drop in support for the tobacco tax - 53 percent of likely voters said they will vote for the $1-a-pack hike, down from 67 percent in March. Meanwhile, a ballot measure that would change the state's term limit laws to reduce the time legislators may spend in Sacramento from 14 years to 12 still has strong support, with 62 percent of likely voters backing the proposed change, down from 68 percent in March. Brown's tax initiative - which is likely to appear on the November ballot - is still receiving majority support, with Democrats backing the measure, Republicans opposed and independents split.

...With the Dumbarton Bridge closed all weekend for seismic strengthening, traffic crawling to and across the Golden Gate Bridge because of its 75th birthday party, and Muni's busiest Metro line - the N-Judah - starting a nine-day shutdown Friday, getting out of town could be a sensible strategy.

A federal jury's unanimous ruling Wednesday that Google did not infringe Oracle's patents when it developed its Android software was a major victory for the search giant and a blow to Oracle's efforts to control how others use its Java software. But experts and analysts say it's unclear how much of an impact the verdict will have on the tech industry as a whole. Immediately after the verdict was announced, Judge William Alsup of the U.S. District Court of Northern California dismissed the 10 jurors and canceled the third phase of the trial that was to determine damages. Alsup said he would issue a decision on a related copyright issue within the case next week.

BART would begin late night weekend bus service between San Francisco and the East Bay, run trains an hour later on the Richmond line, add 56 workers, and set aside more money to buy new cars, under a proposed transit system budget. Unlike many transit agencies that are struggling financially, BART is considering a 2012-2013 operating budget of $670 million -- 8 percent larger than last year. That figure includes a $30 million surplus to be used to make improvements. The BART board will hold a budget public hearing at its meeting 9 a.m. Thursday in the third floor meeting room at the Kaiser Center, 20th Street Mall, 344 20th St., Oakland.
