Quite a few right-wingers call themselves constitutional conservatives, but self-described constitutional liberals are pretty rare. Washington Monthly blogger Martin Longman essentially positioned himself as one in a Friday post, arguing that there’s no need for modern Americans to interpret the Constitution the way the Founders did, but contending that the Founders would be OK with that because they knew “we could amend the Constitution, [or] pass new laws, [or] judges would make rulings consistent with changing standards about privacy and human sexuality and crime and punishment.”
“The modern world,” wrote Longman, “would blow all of [the Founders’] minds and they would probably struggle to make sense of it.” He claimed, for example, that George Washington wouldn’t “believe that the NRA was being reasonable at all” in its opposition to proposed gun restrictions.
Piggybacking on Paul Waldman's "Who Do You Hate?" American Prospect post in which Waldman singled out Sarah Palin and Scott Walker for special scorn, another liberal blogger, the Washington Monthly's Ed Kilgore, reflected on the politicians ("usually, though not always, on the right side of the fence") who inspire in him "regular fear and loathing."
One of Kilgore's choices is an entire group, "the self-styled 'constitutional conservatives'...[who] don’t just want to beat progressives (and moderates) politically, they want to define us right out of existence."
