In a perfect example of the Law of Unintended Consequences, a Federal campaign reform law has created confusion about whether or not it applies to blogs, which are normally written by just one or perhaps a handful of people.
The Federal Election Commission (FEC) officials don't even agree on what is correct. Some commissioners think bloggers and Internet campaigning generally are exempt, and others disagree.
Strictly interpreted, any time a blogger discussed politics, it would potentially generate paperwork and FEC reports, and taking political ads on a blog site would trigger more reporting.
Since bloggers generally don't make a full time living from their blogs, and most do it as a no-income or low-income sideline, any reporting requirements at all would force them to avoid any discussion of politics, abridging their right to free speech.
