On Tuesday night, after an important and historic victory in the Wisconsin Presidential Primary by Senator Barack Obama, I appeared on the MSNBC post-election program. “Hardball” host Chris Matthews, began grilling me on Senator Obama’s legislative record.

And my mind went blank. I expected to be asked about the primary that night, or the big one coming up in Texas on March 4, or just about anything else about process. When the subject changed so emphatically, I reached for information that millions of my fellow Obama supporters could recite by heart, and I couldn’t summon it.
