Today's Ted Cruz news: "On a day of dueling presidential announcements, conservative neurosurgeon Ben Carson was the clear winner in Facebook engagement, driving nearly three times the traffic of former Hewlett-Packard executive Carly Fiorina. ... In relation to other GOP contenders, both fall on the lower end of engagement. Florida Sen. Marco Rubio got about 1.3 million interactions from 695,000 people, Kentucky Sen. Rand Paul got about 1.9 million interactions from 865,000 people, and Texas Sen. Ted Cruz came out on top with 5.5 million interactions generated by 2.1 million people." Read more from CBS News.

Cruz has assembled his team in South Carolina, the first southern primary state. "His campaign named three co-chairs -- State Sen. Lee Bright, R-Spartanburg; State Rep. Bill Chumley, R-Spartanburg; and former Dorchester Sheriff Ray Nash, according to a copy of a letter obtained by The State. Bright ran for the U.S. Senate last year against incumbent Republican Lindsey Graham but lost in the primary. Cruz's grassroots team also includes another candidate who failed to unseat Graham, Orangeburg attorney Bill Connor." Read more from The State.
