An experimental online poll of California voters by the University of Southern California's Dornsife College of Letters, Arts and Sciences has found strong support for Gov. Jerry Brown's tax increase ballot measure - almost identifical, in fact, to a simultaneous telephone poll.
The USC/Dornsife telephone poll last month found that 64 percent of the respondents supported Brown's package of sales and income taxes with 33 percent opposed. The online poll found a 63 percent-30 percent split.
Both surveys were based on a capsule description of Brown's plan. The online poll also tested the official ballot summary of Brown's plan and found 60 percent in support and 30 percent opposed.
Both polls found scant support for a rival income tax measure sponsored by civil rights attorney Molly Munger and the PTA. It was 32 percent in the telephone poll and 24 percent in the online survey.
Dan Schnur, the poll's director, said the online survey was an experiment to test methodology and ask more in-depth questions than the phone version asked. Other questions in the online poll dealt with President Barack Obama's approval rating, online privacy issues and Internet piracy.
