This is what McCain-Feingold has wrought:

The Republican National Committee is warning television stations across the country not to run ads from the MoveOn.org Voter Fund that criticize President Bush, charging that the left-leaning political group is paying for them with money raised in violation of the new campaign-finance law.
...
And in a bit of political one-upmanship, the letter [from the RNC] quotes the presumptive Democratic nominee, Sen. John Kerry, as saying that the objective of the new law "is to eliminate altogether the capacity of soft money to play the role that it does in our politics.

The Democrats deserve this for voting for McCain-Feingold; the RNC has shamed its party by taking complicity with McCain-Feingold, which Bush signed, to a new level. I read about the use of technicalities to suppress to suppress legitimate political speech in places like Venezuela. To read about them here jars me such that I do not hesitate to use the epithet "un-American." A misguided quest for fairness has lead to a pernicious policy that is neither free nor fair. I don't think making George Soros more influential in the Democrats' campaign, relative to groups like MoveOn.org, is what any reformer had in mind.
