Story highlights

Religious voters made up about 75% of South Carolina Republican votes Saturday, according to early exit poll results

Many Republicans also did not make up their mind until the last week before the primary

Washington CNN —  

Religious voters are turning out in high numbers in South Carolina, according to early exit poll results there, and about half of all Republican voters said they made up their mind in the last week.

Evangelical or born-again Christian voters made up 74% of the electorate there, according to early polls. In Iowa, more than the 64% of Iowa Republicans identified as such.

Conservatives clearly dominated the results there, with 81% saying they identified as very conservative or somewhat conservative.

Many Republicans also made up their minds on who they would vote for in the past week – with 46% saying they decided late in the race.

And when asked which candidate “ran the most unfair campaign,” 41% said Trump compared with 32% for Cruz.

About 53% said they feel “betrayed by the Republican Party,” according to the results, and about 40% of voters said they are “angry” at the federal government. Cruz and Trump both fare well among the voters who feel “betrayed” by their party, and Trump wins 42% of the voters who say they are angry at the federal government.

South Carolina Republicans also split over whether the next president should have experience in politics or be from outside the political establishment – 48% say they should be experienced, 47% said they should be outside the establishment.

Among those who were looking for an outsider candidate, Trump clearly dominated with 61% support.

However, 53% of South Carolina Republicans say immigrants working in the U.S. illegally should be allowed to apply for legal status, compared to 44% who say they should be deported to their home countries.
