Rice was among 10 GOP representatives who joined Democrats on January 13 in voting to impeach Trump for his role in the violence a week earlier at the US Capitol. A Senate trial is expected in February. 

A day after his vote, Rice — who represents South Carolina's 7th District, an area that voted heavily for Trump — told The Associated Press “it hurts my heart” to have gone against the president, but he decided to back impeachment after seeing what he characterised as Trump's inaction during the Capitol Hill riot. 

State party-level censures aren''t common in South Carolina. The GOP in 2009 issued one to then-Governor Mark Sanford after he fled the state for five days to visit a lover in Argentina. 

In 2009 and 2010, several county-level Republican parties censured Senator Lindsey Graham for his willingness to work on bipartisan deals, with one county deriding Graham's “condescending attitude” to the party's grassroots organisers. 

The censure is a symbolic expression of disapproval that some warn could have electoral consequences for Rice, who has represented the 7th District since its creation in 2012. 

Long a reliable backer of Trump's policies, Rice campaigned with the president and, according to FiveThirtyEight, voted 94% of the time in favour of Trump-backed legislation — the highest percentage among South Carolina's current delegation. 

In his only primary since first elected in 2012, Rice won with 84% of the vote. He's been reelected each time with at least 56% of votes cast. Now, Rice is all but sure to face at least a handful of primary challengers, with one formally creating an exploratory committee this past week. 

Rice told the AP he knew he'd likely face a difficult primary and that the impeachment vote could potentially cost him his seat: “If it does, it does,” he said. 

Dreama Perdue, the Republican chairwoman in Rice's home county of Horry, said she's fielded hundreds of phone calls from people displeased with the congressman's vote. 

"The people in the district are just very, very upset that Congressman Rice would do this, knowing how much we support the president in South Carolina, and in the 7th District, and in Horry County," Dreama Perdue told the AP. 

"He told me he voted his conscience. These people did not vote for you to vote your conscience; these people voted for you to support us and our district and the president."
