Alaska has had one member in the U.S. House serving at-large since the delegate's position was created in 1905.  How does gerrymandering factor into that?

If you really want to dig into something, look up a (state) Supreme Court case from the late 1960s called Begich v. Jefferson.  Because of the outcome of that case, Young and Nick Begich were on an unavoidable collision course.  I think the real essence of that rivalry was lost to history when Begich disappeared and attitudes shifted.
