President Obama's approval numbers are starting to mimic Mitt Romney's.

According to a new Economist/YouGov poll, it's the rich -- not the poor or middle class -- who back Obama more despite his 2012 campaign attacking the rich.

The poll found that fewer than half of those with incomes less than $100,000 per year approve of Obama's performance, while he enjoys a 54 percent approval rating among those with incomes higher than that.

Those earning less than $40,000 a year disapprove of the president's performance, 51 percent to 45 percent. Those earning $40,000 to $100,000 disapprove by a rate of 50 percent to 48 percent.

"A largely jobless recovery coupled with a Quantitative-Easing-fueled stock market rally seems to earn more smiles from the upscale among us, fewer from the working class," said the pollsters.

YouGov conducted the poll April 27-29 among 1,000 Americans aged 18 and over.
