TPM reported that Obama picked up two more superdelegate, Texas Democratic Party chairman Boyd Richie and his wife. An interesting tidbit in the Dallas Morning News article is this:

"Texas is sending 228 delegates to the national convention. Almost all of them are pledged according to primary and caucus results, except the superdelegates and three others the chairman gets to select."

Seems likely that Obama will actually get a net gain of five, rather than just two.
