With every big name in national Tea Party politics lined up behind Ben Sasse in the Nebraska Republican Senate primary, a disinterested observer could be forgiven for assuming that Shane Osborn was some GOP Establishment today.

Except, that’s not the case. Osborn, a Navy veteran who was once captured and interrogated by the Chinese military for several days, served one term as the elected Nebraska treasurer, stepping down in 2011 rather than run for re-election. He has never lived in Washington aside from a 15-month assignment to the Navy Yard following his final deployment to Afghanistan.
