He’s not familiar to me. the article says he was one of two GOP Senators to publicly back Hagel for nomination.
OTOH, he was chosen by the Governor as Hagel’s replacement, and it’s pretty hard to not endorse someone you have replaced.
Is he a RINO, as I suspect? Maybe a placeholder for the Gov? Does anyone from Nebraska know if someone better might be put forward?
You may be right. On the other hand, maybe he just did not want to continue to associate with the graft, corruption and crooks that make up Senate. Scratch Senate, make it the Congress and Washington D.C.
