Today’s luncheon at Netroots Nation is sponsored by MoveOn.org. And before one can enter the cavernous convention ballroom, agents from ICE (Immigration and Customs Enforcement) will stop you and demand identification. “Joe, you don’t look like you’re from around here. This ID is unacceptable. I’m going to have to ask you to step aside and be photographed for our records.” Everybody laughs and plays along, but the point is made.
