“I think it’s the negative advertisements that have kind of been turning voters away,” said Berkeley IGS poll director Mark DiCamillo. “People who haven’t seen the ads are about evenly divided, but people who’ve seen a lot of ads are against it. So, the advertising is not helping.”

And that’s bad news for both ballot measures. The poll found that Proposition 26 earned only 31% support from likely voters, compared with 42% opposed, according to the Berkeley survey of 6,939 likely California voters. Proposition 27 fared even worse — 27% of likely voters in support and 53% opposed.
