The ACLU has come out in support of the Obama administration’s mandate requiring the Catholic Church to change its position on contraception. I can’t say this surprises me. The ACLU has been very weak on religious freedom; opposing it more often than defending it.
POSTSCRIPT: A new Rasmussen poll finds that the public opposes the mandate 50-39.

The ACLU will only defend causes that are ideologically liberal. There is no room for conservative causes or freedom of religion from state control with the ACLU.
I think that’s a bit of an overgeneralization. For example, the ACLU opposed McCain-Feingold. But I’ll agree that the ACLU has a strong preference for liberal causes. What galls me about this isn’t that they are taking a pass on freedom of religion (that I would expect), but that they are actively opposing it.
