Well, this wasn't exactly hard to predict. I'm sure the RNC is thrilled. From CNN:
Iowa Rep. Steve King, whose hard line immigration rhetoric has angered some of his fellow Republicans and delighted Democrats eager to keep Hispanic voters in their fold, is quietly planning meetings with political activists in the early presidential primary state of South Carolina, CNN has learned.

King will travel to the state in late August to attend the Charleston Meeting, a closed-door gathering of right-leaning politicians and business leaders organized by author and activist Mallory Factor, two Republican sources said.

My favorite part is where they say he's "quietly" planning things.
