I don't agree with any of these GOP Governors/AGs on refusing to uphold their constitutional amendments. Me, I would have told these federal judges to pound sand.
Again, the distinction is between the role of a Senator and a Governor. Weeks before a critical election, what was Walker going to do? Sometimes you have to live to fight another day. At that point and time, that wasn't a hill to die on, also knowing that the issue is and will take care of itself.
