A new poll shows lower approval numbers for most politicians, but not for Gov. Nikki Haley.

Only 15 percent of South Carolina adults approve of the way Congress is doing its job, while 38 percent approve of the General Assembly, according to results of a new Winthrop poll released today. Thirty-six percent disapproved of the Legislature.

Haley’s approval rating among Republicans and those leaning to the GOP rose from 66.8 percent in February to 69 percent. Among all state residents, her number ticked up 1 percent — to 43.5 percent.

U.S. Sen. Lindsey Graham received a 44 percent approval rating among state voters but saw his rating among Republicans dip from 72 percent in February to 58 percent.

U.S. Sen. Tim Scott has a 40 percent approval rating among registered voters, while about 22 percent disapprove of his performance. About 40 percent still aren’t sure how he’s doing.

Scott, Graham and Haley are all up for election next year.

The poll surveyed 1,069 South Carolina adults from April 6-14. Its margin of error is plus or minus 3.5 percent.
