One way to figure out whether someone's policy preferences are based on considered principles, or if they're just a symptom of partisan loyalty, is to see if those preferences swing with the partisan winds.
So, what about Republicans in general -- are they principled citizens whose agendas have been developed over a long period of thinking through the facts? Or are they gullible dupes who just embrace whatever position their favorite propagandists are pushing at the moment? And how about Democrats?
Here's a telling set of graphs:
As you can see, among those who lean Democrat, there's been a gradual evolution of opinion regarding free trade deals. Back in 2009, most people on that end of the spectrum thought free trade agreements tend to be a good thing for the US. Gradually, over the following years, that majority grew. But there were no sudden reversals.
The real action is on the Republican side. At first, Republicans thought free trade agreements have generally been a good thing for the US -- around 57% in 2009. Then Obama signed three trade deals, with South Korea, Panama, and Columbia, and pushed for a few others. Immediately, a slight majority of Republicans thought free trade agreements have generally been bad for the US. Then, over the next few years, Republican sentiment return to its historically pro-free-trade position.... until Trump became the leading Republican figure and took the opposite position, with most right-wing propaganda outlets taking their cues from him.
At that point, the Republicans moved dramatically against free trade. By the start of 2017, only 29% of Republicans thought free trade agreements have tended to be good for the US -- down from a majority just three years earlier. But then Trump started negotiating trade deals himself, culminating in signing a deal with Canada and Mexico. Republican opinion about trade deals obediently improved -- moving 14 points and it's now closing in on being a majority again.
That's not to say the Democrats are totally free of the partisan impulse on the topic. Maybe somewhere on that Democratic graph is a little hiccup that could be attributed to a politician they like or dislike having taken a particular position. But it's nothing like the crazed swings among the Republicans, most of whom seem completely untethered to any principle other than liking the Republican leadership and disliking the Democratic leadership.
