I think H.R. 1606 would have a very good chance of passing if it ever comes up for a vote. Many politicians now have blogs and websites. Only an idiot would tell politicians not to talk about their opponents during an election, anyway. I think this comes from McCain's loss in the 2000 primaries. He's thin-skinned and doesn't like people saying things that could cost him votes, so this is his way of getting payback against the GOP leadership for "costing" him the election.
If FReepers could just stop their brawling for a minute or two and contact their representatives to get H.R. 1606 to a vote and have them vote FOR it, then we can get back to our beloved brawling around here.
Otherwise, the following occurs...
If H.R. 1606 fails to become law, your Web site or blog could be shut down for the 30 days prior to a primary election and the 60 days prior to a general election should you express "electioneering communications." And any political e-mail you send during those times supporting or denouncing a candidate could also be disallowed."
