According to Ralph Neas and the Election Protection monitors, "The notion that the 2004 presidential election ran "smoothly" is a myth. In fact, the system is flawed, and significant barriers to the ballot box remain, especially for minorities and the poor. Particularly in urban districts with too few voting stations, lines were up to 10 hours long. These excessive bottlenecks disenfranchised untold thousands who could not afford to wait that long and had to return to their jobs or children before reaching the voting booth."
