When is that, the fall? :-)

Ha Ha, but still, a good question. I figured that if a pre-emergent
works on crabgrass but not regular grass, and must, by definition, be
used before crabgrass emerges, then after a certain time interval it
will be safe to stop using it and I can seed regular grass.

From what I read, corn gluten meal works on a physical level by
draining moisture from seeds and cracking them open. Hopefully that
will affect the crabgrass. Then, once the crabgrass seeds are all
desiccated and cracked, I can put down some regular grass seed and
hope for the best.
