Rep. Steve King’s Iowa Freedom Summit last week was not the most fortuitous launch for Republican presidential hopefuls, but it could have been worse. The Iowa congressman has embarrassed himself and the GOP with his anti-immigrant rhetoric over the years, which is no doubt why some prominent would-be candidates had “scheduling conflicts” that kept them away. Missing from the forum were Jeb Bush, Marco Rubio, Rand Paul and Mitt Romney, whose missteps on immigration last time helped cost him the election.
