Manchester, New Hampshire (CNN) - Sixty-five percent of New Hampshire residents disapprove of President Obama's handling of the economy, according to a new poll.
The American Research Group's September 2011 Quarterly New Hampshire Poll also found the president's approval rating in the first-in-the-nation primary state is pegged at 31%.
Dante Scala, a political science professor at the University of New Hampshire, said the notable shift in Obama's support is among undeclared, or independent voters. Sixty-seven percent of undeclared voters in the state say they disapprove of how the president has handled the economy.
Even though New Hampshire's unemployment rate is much lower than the national figure, Scala said voters here are affected by rampant displeasure in the economy.
Obama lost New Hampshire's primary to Hillary Clinton in 2008 but triumphed over John McCain here with 54% in the general election. The state carries four electoral votes.
The American Research group poll was conducted by telephone from September 25-29, surveying 547 adults in New Hampshire. The sampling error was plus or minus 4.2 percentage points.
