There you have your solution Idaxit! Leave the US, split the state and rejoin the union (US) in case you still feel like. ...or maybe don't and just use the chance and bring your legislative and judiciary into the 20th century. You will be still a ahead of the then neighbouring US at least by a century. Maybe even other states feel to follow the lead. I've heard Florida is always easy to convince for such a move; maybe skip the war declaration this time. ;-)

Disclosure: I have no clue about the underlying political/"cultural" differences of Idaho in contrast to the rest of the states...or Florida for this matter.

The only problem is, it's been pretty well established by the Civil War that a state cannot secede. Otherwise good idea.

In practice, though, would the 49 remaining states invade Idaho & force them back in? The middle of the state is pretty wild & mountainous.
