Isn't Denunciation Coordination?

Kausfiles has a point about the SwiftVets ads and BCRA, which since his permalinks are questionable I'll quote in full:

If President Bush were to tell the Swift Boat Veterans, "Those are great ads. Please run more of them," he'd immediately be accused by the Kerry campaign (and maybe the Federal Elections Commission) of illegal "coordination" with an allegedly independent political group. ... Now suppose Bush did what Kerry and David Broder want him to do and told the Swifties "Those are terrible ads. I call on you to stop running them." Why isn't that also illegal coordination? Coordination involves telling someone when to start and also when to stop, no? [I'm indebted to alert kf reader S.K. for this point.] ...

Does this mean Broder's idea that

candidates ought to be judged by their willingness to tell their supporters when they have crossed the line

is untenable, because it in effects asks the candidates to start coordinating illegally? I'd like to think not--the only way to allow free speech by independent citizens while limiting the role of big money in politics seems to be to preserve some rule against "coordination" of the independent citizens by the official, regulated campaigns. But it will probably have to be a rule loose enough to allow candidates to publicly approve or condemn particular independent ads--in other words, loose enough to allow some de facto, long distance coordination. The hope, I suppose, is that it will always be clumsy, imprecise coordination, because the candidates still wouldn't control who shows what ads initially--and even in public the candidates couldn't get too specific (e.g., "I like that ad but I'd pull it from the Denver market and run it in Orlando instead"). ... 12:06 A.M.

Seems reasonable to me. At least the first part. I rather like having uncoordinated, uncoordinatible groups running around. It feels like...freedom. How stultifying would the campaign be right now if everything were left to the national parties?

By the way, given Swiftee-in-Chief John O'Neill's not-so-kind words for President Bush (he describes him as "an empty suit") it seems increasingly clear to me that the SwiftVets, despite the support of many individual Republicans for the organization, are not, in fact, a Bush campaign front.
