SPARKS, Nev. — By the end of Day Two in San Antonio, my brain was fried, but the good kind of fried.
My task at the "Stand for Change" rally was to supervise the ticket-takers. They never tell you about the logistics of a candidate event in campaign school; it's more along the lines of on-the-job training. Estimates put the crowd of people expected to hear Sen. Barack Obama (D - Ill.) speak anywhere from 5,000 to 7,000. That meant two things: a long line of people and various personality types with which, to deal.
