27. No, the Baja is caused by North America ripping itself apart.
The San Andreas is slowly pulling the western edge of North America northward and eventually away from the rest of the continent. At some point millions of years from now, Los Angeles, San Francisco, and the rest of the coast west of the San Andreas will exist on an island. Baja is merely the southern portion of that future island, which has pulled away before the northern half has.

By the way, the actual "rift" extends all the way to Palm Desert. If you've ever wondered where all the dirt from the Grand Canyon went: It flowed down the Colorado and was dumped into the northern end of the Gulf of California. Eventually, enough sediment flowed out that it completely filled the northern end of the sea and created the Imperial Valley. Still, the rift is there, gradually widening, just covered by some sediment.
