A reader notices this in a recent Ken Silverstein piece:

In seeking to woo conservatives, Romney has also used his personal PACthe Commonwealth Political Action Committeeto contribute lavishly to several national pro-life groups, the Federalist Society, the National Review, and the Heritage Foundation, among others.

Is the National Review thing true? Now I don't believe for a second that NR endorsed Romney for anything other than the reasons they cited. It certainly makes sense for purely ideological and partisan reasons. But I do think it's a legitimate question to ask them to disclose how much money a leading Republican candidate has donated in the past few years. Full disclosure and all. If Barack Obama or Ron Paul had given me a large donation before I endorsed them, I'd feel obliged to disclose. Are the rules different for a magazine than for a blogger?
