Blogging Could Cause a Two-Year Jail Term?

Greg Pollowitz at NRO Media Blog sends the alert (via The Volokh Conspiracy) that Rep. Linda Sanchez, Democrat of California, has proposed a bill that would make it a federal felony to use blogs, text messages, and Internet messaging ("electronic means") to harass someone and cause them "emotional distress." Eugene Volokh pulls these snippets out of H.R. 1966:

Whoever transmits in interstate or foreign commerce any communication, with the intent to coerce, intimidate, harass, or cause substantial emotional distress to a person, using electronic means to support severe, repeated, and hostile behavior, shall be fined under this title or imprisoned not more than two years, or both....

["Communication"] means the electronic transmission, between or among points specified by the user, of information of the user's choosing, without change in the form or content of the information as sent and received; ...

["Electronic means"] means any equipment dependent on electrical power to access an information service, including email, instant messaging, blogs, websites, telephones, and text messages.

Volokh asked:

What are Rep. Linda Sanchez and the others thinking here? Are they just taking the view that "criminalize it all, let the prosecutors sort it out"? Even if that's so, won't their work amount to nothing, if the law is struck down as facially overbroad -- as I'm pretty certain it would be? Or are they just trying to score political points here with their constituents, with little regard to whether the law will actually do any good? I try to focus my posts mostly on what people do, not on their motives, but here the drafting is so shoddy that I just wonder why this happened.
