Looks like America is regretting not having voted for Mitt Romney in the 2012 presidential election just about now.

A Quinnipiac University poll released Wednesday shows that a third of voters, 33 percent, believe Barack Obama to be the worst president since World War II, with his predecessor, George W. Bush, trailing behind with 28 percent at the bottom of a poll on worst post-war presidents.

Richard Nixon came in at third place with 13 percent of the vote, with Jimmy Carter, who 8 percent of voters said was the worst president in the time period, coming in fourth.

While 35 percent of voters said Ronald Reagan was the best president since World War II, receiving nearly twice as many votes as any other former president, Bill Clinton came in second place at 18 percent, with John F. Kennedy coming in third with 15 percent of the vote, according to Politico. Obama trudged in at fourth with mere 8 percent voters claiming him to be the best president.

Two years into President Barack Obama's second term, his administration's handling of everything from the economy to foreign policy has continuously been criticized, leaving him with the worst marks of any modern U.S. president since 1945, Reuters reported. "Over the span of 69 years of American history and 12 presidencies, President Barack Obama finds himself with President George W. Bush at the bottom of the popularity barrel," said Tim Malloy, assistant director of Quinnipiac University's polling unit.

The survey comes as Obama in recent weeks has found his popularity at the lowest levels of his presidency. Although the president's job approval rating rose to 40 percent, up from 38 percent in December, a majority of voters rated him with largely negative marks in key areas of the economy, foreign policy, healthcare and terrorism.

Meanwhile, 45 percent of voters believe the nation would be better off had Mitt Romney defeated Obama in the 2012 presidential election, compared to 38 percent who said the country would be in worse shape.

The telephone survey, conducted June 24 to June 30, with 1,446 registered voters had a margin error of plus or minus 2.6 percentage points.
