President Barack Obama gets a negative 45 – 49 percent job approval rating, compared to 48 – 45 percent positive in a May 1 survey by the independent Quinnipiac (KWIN-uh-pe-ack) University, conducted before the IRS allegations surfaced.

The president’s biggest drop is among independent voters, who give him a negative 37 – 57 percent score, compared to a negative 42 – 48 percent May 1. He gets a negative 9 – 86 percent from Republicans and a positive 87 – 8 percent from Democrats, both virtually unchanged. Women approve 49 – 45 percent while men give a negative 40 – 54 percent score.

Americans are divided 49 – 47 percent on whether Obama is honest and trustworthy, down from 58 – 37 percent, the last time Quinnipiac University asked the question September 1, 2011.
