As I briefly mentioned at lunchtime, the President spoke at a convention of the United Auto Workers in Washington today, and I strongly suspect he had the Michigan GOP primary on his mind.

In a speech that reminded some listeners of his 2008 campaign style, Obama identified with his union audience, mocking Republican charges that workers are a “special interest,” and went after Mitt Romney without naming him.
As Greg Sargent commented:
Obama used the auto-bailout argument as a jumping off point for his larger case: That Democrats and Republicans have fundamental ideological differences over government’s role in stepping in and protecting working people and ordinary Americans against the depredations and excesses of unfettered free market capitalism, and that this all flows from a difference over moral values and priorities.
So you can bet these remarks will spur a new round of conservative recriminations about the president engaging in demagogic class warfare at the behest of union bosses.
