I read a book once - wish I still had it - fellow stressed the importance of the issues involving California statehood. Questions included whether the new state would be slave or free, and of course the fortune in gold being pulled out of the ground. Perhaps the most ticklish was the route of the railroad link, since development and prosperity would follow the right-of-way. Many routes were feasible and different sections of the country were lobbying hard for their favorite one. Many in the north were heap POed to learn that their tax dollars had been used for the Gadson purchase (Tucson), the south's preferred one.
