Based on what rumor? Tesla
Based on what rumor? Tesla would be stupid to put all their eggs in one basket (California) and would be far smarter to spread out, as other automakers and industries do, in order to mitigate losses should they become too vested in one political area. Further, the same logic you're using could be used the other way. If Tesla does build their factory, or make it look like they're seriously considering building it, in a state like Texas where they so far haven't been welcome, but have relatively large sales volumes, it might be the "jobs and income" key to unlock the door and change the rules in that state.
