Cowan was appointed on Tuesday to three committees: agriculture, commerce and small business.

Wait... agriculture? We’re not aware that there are a whole lot of farms in the greater Boston area (though we hear the ivy crops are really thriving), but perhaps he’ll delve more into the other areas of that committee’s jurisdiction, like nutrition, school lunches and the like.

Another committee-related trickle down effect of Kerry’s departure: Sen. Bob Casey (D-Pa.) snagged a spot on the powerful tax-writing Finance panel vacated by the Massachusetts Democrat.
