It could always be worse for U.S. Sen. Lindsey Graham.
He could be as unpopular as Majority Leader Mitch McConnell, or as disliked as U.S. Sen. John McCain.
Instead, Graham has only the third-worst approval ranking in the U.S. Senate, according to poll results out Tuesday from Morning Consult.
Among voters in the Palmetto State, the poll found Graham had a 40 percent disapproval rate and a 46 percent approval rate. Fourteen percent of the state’s residents voiced no opinion.
Compare that with South Carolina's other senator, Tim Scott, who has the approval of 59 percent of the state's voters, while a smaller 19 percent disapprove of his work so far.
Since March 4, Graham has held three constituent town hall events in South Carolina. Each time, Graham faced discord from audience members.
Overall, only two other senators — both Republicans — were more unpopular than Graham.
McConnell, R-Kentucky, was the most unpopular senator, with a 47 percent disapproval rating in his home state and a 44 percent approval rating. Forty-three percent of Arizona voters disapprove of their U.S. Sen. John McCain, while 51 percent approve.
Overall, the most popular senator was Bernie Sanders, an independent from Vermont.
The unsuccessful 2016 Democratic presidential candidate boasted a 75 percent approval rating among Vermont voters and a 21 percent disapproval rating.
Morning Consult surveyed 85,000 registered voters nationwide for its recent poll findings. In the poll, voters were asked whether they approve or disapprove of the job performance of President Donald Trump, their state governor, both of their U.S. senators and their congressional representative. If voters lived a city with more than 10,000 residents, they were also asked whether they approved or disapproved of the job performance of their mayor.
Graham's disapproval rate has remained largely unchanged since Morning Consult polled voters ahead of the 2016 presidential elections. In that poll, Graham had a 40 percent disapproval rate and a 45 percent approval rate.
In that ranking, though, Graham was the sixth-most unpopular senator.
