Even if they flexed their employer muscles, that would only affect local officials. Why would a republican senator from Kansas care if they're going to cut jobs in Virginia?
because he doesn't want local families protesting in front of his local residence embarrassing him in front of all his other big shot neighbors?
I'm sure politicians get as embarrassed as the next person by public shaming, but forgive me if I'm inclined to believe they won't act much on complaints by non constituents.
