Strange how "campaign finance laws" always seem to come down to suppressing speech.

Sounds like there's also serious doubt this is in any way illegal, e.g. this comment by "Daniel Tokaji, a professor of Constitutional Law at Ohio State University":

"A lot of things you and I would consider coordination are not coordination under the law. I don't think sharing polling data is going to be enough to establish that the campaign was materially involved in decisions about content, target audience or timing."

Outlawing "coordination" is a very dangerous slippery slope to go down, as Wisconsin recently showed.
