SACRAMENTO -- A Field Poll released Wednesday shows support for President Barack Obama is falling even in reliably Democratic California, where the shaky economy and persistently high unemployment have created pessimism about the future.

Just 49 percent of registered voters say they are inclined to re-elect Obama, 5 points higher than the number of those who say they are not. In 2008, Obama beat Republican John McCain by a 24-point margin in the state.

The Field Poll finds the Democratic president's job-approval rating in California has slipped to 46 percent, about the same as those who disapprove. Just three months ago, Obama's approval ratio was 54 percent to 37 percent.

One out of five Democrats disapproves, an increase of 10 percentage points since June. Support for Obama has slipped 13 percentage points since then among non-partisan voters, a bloc that will be key to winning the presidential contest in 2012.

Many voters say they are growing disenchanted with Obama's handling of the economy. For the first time since he took office, a majority say they disapprove of how he has addressed the issue while 40 percent say they approve.

California's unemployment rate rose back to 12 percent in July, the second-highest in the nation behind Nevada. Nearly 2.2 million Californians remain out of work.

That has led to an increasingly pessimistic view of the future.

Nearly seven in 10 registered voters told pollsters they believe the country is seriously off track, the largest percentage since the 2008 presidential election that swept Obama into office. Just two in 10 say the country is moving in the right direction, a new low.

The poll has an overall sampling error margin of plus or minus 3.2 percentage points, but it is higher for subgroups. It was based on telephone interviews with 1,001 registered California voters from Sept. 1-12.
