Weird, I never thought of the Republicans as being pro-Union.
Weird, I never thought of the Republicans as being pro-Union.
When exactly? Because thinking back through the history of the party from it's emergence, I can't see any time when I would say that, without some strong geographic, racial/ethnic, or other caveats. Their current status as the party of white working-class resentment is probably the most working-class they've ever been, unless you consider the original anti-slavery focus as a focus on the plight of a particular segment of the working class.
And they aren't. The current crop of Democrats mostly is, even with the continued strength of the pro-globalization factions of the party (which include a substantial faction that is basically neoliberal, but many members of which acknowledge some harms of neoliberal capitalism and see unions as a local mitigation for those harms.)
