HILTON HEAD, S.C., Feb. 10 (UPI) -- Former President George W. Bush is jumping in to help campaign for his brother, Jeb, in South Carolina this week.

"They want a commander-in-chief that will have a steady hand and have a backbone and will support the troops and has detailed plans on how to keep us safe as it relates to Islamic terrorism," Jeb Bush told CNN Wednesday. "Here in South Carolina particularly that's an important issue."


George W. Bush stars in radio ads that rolled out Wednesday, according to The Washington Post.

The 43rd president won the South Carolina Republican primary in 2000. In 2008, Sen. John McCain, R-Ariz., won the primary, and went on to win the Republican nomination. In 2012, former House Speaker Newt Gingrich handily beat out Mitt Romney in South Carolina, but Romney went on to win the party's nomination.

Former Florida Gov. Jeb Bush came in fourth in the New Hampshire primary on Tuesday with 11 percent of the vote, just behind Texas Sen. Ted Cruz, winner of the Iowa caucuses, and just ahead of his Florida rival Marco Rubio.

The South Carolina primary will be held Feb. 20.

So far, Donald Trump leads with 32 percent in South Carolina, according to the RealClear Politics 30-day average of all polls. In second place is Sen. Ted Cruz, R-Texas, with 19 percent, followed by Sen. Marco Rubio, R-Fla., in third place with 12 percent. Bush comes in fourth with 10 percent. However, no poll has taken South Carolina's temperature since Jan. 23, so Bush may receive a boost thanks to his comeback in New Hampshire.
