Nobody won any of these elections by promising to outsource more jobs.
Nobody won by campaigning for more anti-American manipulated trade agreements.
Lots of candidates won by campaigning against high taxes and regulatory burdens, and for free market principles. That is quite different from the globalist Free Traitor® mantra.
Actually, I recall a fair amount of discussion about South Korea, Colombia, and Panama. And as the IBD editorial observes, generally, the candidates favoring FTA’s with those three countries won. Maybe you just didn’t pay attention.
In fact, I even recall seeing a good number of articles about how the Dems were seeking to make trade an issue in order to defeat the oncoming wave.
