The enormous expense of moving a factory is probably the overriding issue here. I have no idea what it would take to move the S&W factory, but in the early 90s I was part of refit of the Arlington TX GM factory, not move mind you, but refit to a new line of vehicles, and that was supposedly costing GM 400million. So I'm guessing to pick up and move a factor would expensive enough to make it financial suicide in all but the most dire of circumstances. They are a for profit concern, and only worry about politics as they affect their bottom line. So they aren't going to move because they don't like the local political leanings of their state's legislature right now. They were there when they became leftist, and will probably be there to see the worm turn to the right.
