5 things we learned from Saturday’s Republican primary results

Gov. Nikki Haley and Sen. Tim Scott join Marco Rubio during a rally Friday at Stall High School in North Charleston.

Here are five quick takeaways from Saturday’s Republican presidential primary:

College of Charleston political scientist Jordan Ragusa said Haley’s support probably netted the Florida senator an additional 4 percentage points.

He based his calculation on research models from races dating back to 1988 involving incumbent governors who made a public pick. Ragusa did his work with two C of C students, announcing his projection three days before the vote.

George H.W. Bush won two primaries in South Carolina, in 1988 and 1992. George W. Bush won in 2000.

All these years later — and after promising a “take it to the bank” win last September — Jeb Bush becomes the first member of the family to lose in South Carolina, previously labeled “Bush Country.” The Bush White House dynasty died here.

In December, Donald Trump used the aircraft carrier Yorktown at Patriots Point to call for a “total and complete” ban on Muslims entering the U.S. until Congress gets a handle on terror threats.

Thursday on Kiawah Island, Trump upped the ante with the Vatican after Pope Francis suggested the New York billionaire is “not a Christian” because he favors a wall to block illegal immigrants-on the Mexican border. Trump called it “disgraceful” for the Catholic leader to question a person’s faith.

Neither incident sparked in-state blowback.

More than 710,000 GOP voters came out Saturday. Since presidential primaries are considered party-building tools, South Carolina further solidified its slot in the Red State column.

The rise of political action committees that can spend money to support a candidate — without ever officially coordinating with an official campaign — is the new conduit for throwing mud.

Mail-outs and TV ads played a role, but it was the recorded home phone message that dominated the political arms race. Some voters reported being bombarded by upwards of a dozen or more calls a day, receiving slanted messages about abortion, gay marriage and the Confederate flag in attempts to tarnish the opposition.
