President Barack Obama's disapproval rating has soared to 54 percent in Virginia, which was a battleground state the Democrats won in 2008.
Political observers say he needs the Old Dominion to win re-election next year.
The Quinnipiac University Poll released Thursday shows only 40 percent approve of Obama's performance, down from 48 percent in the same survey taken in June.
Of those polled, 51 percent said he does not deserve a second term.
The results coincide with other polls revealing a continuing slide in the president's popularity during a slow, troubled economy.
Obama's popularity among independent voters is in trouble too. Sixty-three percent of voters who call themselves independent disapproved of the way Obama is handling his duties, while only 29 percent approved.
The polling was done during telephone interviews with 1,368 registered voters from Sept. 7-12. The survey's margin of sampling error was plus or minus 2.7 percentage points.
