A Legislative and Political History of ERISA Preemption, Part 1
This article recounts the key role of preemption issues in Congress's decision to pass ERISA. Until shortly before ERISA's enactment, employers and the AFL-CIO opposed comprehensive pension reform legislation.

Their support made passage of such legislation a virtual certainty.
