About this Poll

These are findings from an Ipsos poll conducted October 2-4, 2010 on behalf of Reuters. For the survey, a representative,
randomly selected sample of exactly 600 adults aged 18 and older across California who are registered voters was
interviewed by Ipsos. With a sample of this size, the results are considered accurate within 4 percentage points, 19 times out
of 20, of what they would have been had the entire population of registered voters in California been polled. Likely voters
(reported on for ballot questions only) are defined as individuals currently registered to vote, who voted in the 2008
Presidential election, are a 7-10 on a 10-point likelihood to vote scale, and are interested in following news about the
campaign ‘a great deal’ or ‘quite a bit.’ Individuals who did not vote in the 2008 Presidential election qualify as likely voters if
they are registered to vote, are an 8-10 on a 10-point likelihood to vote scale, and are interested in following news about the
campaign ‘a great deal’ or ‘quite a bit.’ Out of our sample of 600 registered voters, 448 are likely voters. With a sample of this
size, the results are considered accurate within ±4.7 percentage points, 19 times out of 20, of what they would have been had
the entire adult population in the U.S. been polled.
