House officials would draw the name of each member. Like the NFL, the incoming lawmakers would be"on the clock." They’d have 15 minutes to select their office. The exercise sometimes meant freshmen and incoming aides would sprint down the hallways to check out the best digs available, then race back to report which office they took . Sometimes an office they wanted was just taken. So they’d have to shift gears. You may have been looking to draft a tight end.
The least-desirable offices in Congress used to be on the fifth floor of the Cannon House Office Building across the street from the Capitol. And freshmen used to wind up on the top floor of Cannon almost exclusively.
