In politics, things go too far or not far enough, politicians push some idea far beyond the limits of its applicability or they don't push it at all.
Somebody pointing out that President Trump can't do this with every company that wants to cut and run puts a damper on expectations that might otherwise get out of hand.
It can also act as a spur to come up with more comprehensive policies for dealing with runaway factories and to put those policies into effect.
If Donald Trump can have dinner with Mitt Romney twice, he probably doesn't hold a little constructive criticism against Sarah Palin.
“I don’t agree with her, but she has every right to speak her mind.”
Quite true, but the timing makes no sense except that perhaps the comments are self-serving since Trump has yet to have ANY AUTHORITY to act under the powers of the Presidency. If things were really coming off the rails after Trump had assumed the office it would be a different matter, but here she’s just pissing into the wind for her own devices.
