For example, there's the little-understood but dangerous provision limiting "coordination" between candidates and, yes, citizens. You have to be a lawyer to understand the nuances here. But in essence the bill redefines what is illegal "coordination" to include "any general or particular understanding" with a candidate by a group that later campaigns on his behalf.

So let's say you're the AFL-CIO, and you meet to lobby a Member of Congress on a looming trade bill. If the union later ran issue ads for or against that Member at election time, or ran phone banks or sent out voter guides, that Member might well be in violation of the law's new "coordination" ban.

At a minimum, that candidate would almost certainly be subject to legal harassment from his opponent, in the form of petitions for probes from the Federal Election Commission. This threat to free speech and the right to assembly is egregious enough that it is opposed by, among others, the ACLU, the AFL-CIO and the National Right to Life Committee.
