President Obama's approval rating has hit an all-time low, according to a new poll from Quinnipiac University.
The survey measured Obama's approval at just 42 percent, with 48 percent of voters disapproving of the job he's doing in office.
The 42 percent approval number marks a four percentage-point drop over the past month. A Q-poll released March 3 had Obama at 46 percent approval; 45 percent of voters said he didn't deserve a second term.
Obama is now in a dead heat with a generic Republican challenger, trailing an unamed Republican in a hypothetical 2012 match-up 36 percent to 37 percent.
"President Barack Obama's approval numbers are at their lowest level ever, slightly below where they were for most of 2010 before he got a bump up in surveys after the November election and into the early part of this year," said Peter Brown, assistant director at the Quinnipiac Polling Institute.
Brown pointed to Obama's overall negatives on the deficit, economy, foreign policy and healthcare as driving up his disapproval numbers.
The poll also gave Obama negative ratings on the military action in Libya. Overall, voters oppose the nation's involvement in Libya — 47 percent to 41 percent — and a full 58 percent said Obama has not clearly articulated the goal of U.S. involvement.
The president has taken heat from both Democrats and Republicans for his handling of the Libya conflict, with critics questioning the clarity and duration of the mission and demanding to know why Congress wasn't consulted before the president took action.
Sixty-one percent of respondents in the poll said removing Col. Moammar Gadhafi from power is not worth having American troops "fight and possibly die."
The poll surveyed 2,069 registered voters nationwide from March 22 to 28 and has a margin of error of plus-or-minus 2.2 percentage points.
