Democrats target Trump on trade

“When we say renegotiating NAFTA, we mean a transformation, something substantial, not just going through the motions,” Sen. Robert P. Casey Jr. (D-Pa.) told union leaders recently, referring to the administration’s talks over the North American Free Trade Agreement.

For Democrats, Casey’s pitch signals a wholehearted revival of their labor roots and a sharp departure from the free-trade tilt of the past two Democratic presidents, Barack Obama and Bill Clinton.

The change may also be necessary. While progressive activists are highly motivated against Trump and some suburban voters are increasingly uneasy about Trump’s disposition, many working-class voters remain resentful of globalization and have lingering appreciation for Trump’s populist appeals.
