This seems to be the hot topic in the liberal blogosphere but I can't really muster up strong feelings on the subject. But, I do think the power of single interest groups is overrated. If NARAL "drove" Langevin out of the RI race then that says more about Langevin than NARAL, I think. Yes, there are examples of single issue interest groups shooting their causes in the foot at times but to me NARAL's endorsement of Chafee (post-Langevin dropping out) is really an example of a good use of an opportunity to prove their necessary non-partisan bona fides in a way which won't have much of an impact on the election itself...
