1. Gun control. Once upon a time, any murderous gun rampage was a "Start your engines" signal to liberals to campaign for new gun control measures. Perhaps it still happens on the margins of politics these days, but not a peep (as far as I know) from the most prominent mainstream Democrats.
2. Abortion. In the Elena Kagan confirmation process (and before that, Sotomayor). It did get a mention, but almost none, taking a back seat to many other issues. I agree, however, that abortion probably explains Ben Nelson's vote.
3. How about: Al Sharpton, or Sharpton's heir. Is there anyone today playing the role that Sharpton played in the 1980s and 1990s? At least, with a similar amount of media attention?
4. Well, of course, when the White House finishes a long day of plotting to take everyone's guns away (see item #1, and really item #2 as well), they relax by plotting to reimpose the Fairness Doctrine. But surely this one isn't barking because of a media conspiracy to keep it quiet.
