I remember testifying in front of the House Immigration Subcommittee a couple of years ago and Steve King sat directly facing me. My topic of testimony - the need for an appeals board for consulate decisions - wasn't juicy enough for the Iowa Republican and he went after a friend testifying on an illegal immigration reform measure. At the time, I didn't know much about King, but in the years since he's clearly taken on the most vocal anti-immigration role in Congress, only rivaled by his Iowa counterpart in the Senate, Charles Grassley.
But while King has coasted to reelection in prior elections, re-districting has added a lot of independents to his district. And a high profile Democrat has decided to take him on. The race is shaping up as one of the more interesting ones in the House this year.
