Gail Heriot posted this on Instapundit. The comment thread there so far is a shining example of sheer ignorance and bad faith attacks on Arkansas Republicans. I don't care to create a Disqus account to comment there, so I thought I might say something useful here, even if it is by no means a complete answer.
Walmart is headquartered in Bentonville, AR, and is a chunk of the state economy. Whenever the Republican dominated legislature takes up conservative legislation to which the woke rulers of the Walmart empire object, Walmart implicitly threatens to take their money somewhere else.
I'm not saying the Republican politicians are right or wrong to take this into account. I'm just saying it's part of the political calculus there.
