I have raced, but not regularly and not seriously.
Commuting definitely helps to maintain that base level of fitness that makes it way easier to build on for a race or event. I do a century or two every summer, and coming out of the winter with the 1800 miles that I put in commuting already under my belt makes preparation for an event like that much, much easier than starting from scratch.
I try to work in intervals or other sprints into my commute a couple times a week, and treat (the ride home especially) like a short training ride. I would say that it could certainly be helpful to your race performance...assuming that you don't get hit by a car.
