The folks downvoting you have obviously never been in the rooms when RFPs are drafted. I've been in the room half a dozen times and in almost every case the RFP is written so one particular firm will win the bid, and at most 1-2 other firms are even qualified to respond.
Edit: Once while sitting on the private sector side of the table (yes RFPs were often drafted in consultation with the company that would eventually win them, if just informally), a [state] government employee expressed concern over the wording of a particular requirement because he was worried that it would open the door to our primary competitor being qualified to fulfill the bid.
