A lot of Californians are Republicans, too. Are you contending that only {or primarily} Liberal Californians are prone to move and only to NV, CO and NM?
are western states like Arizona et al, becoming more liberal, or more conservative? look at who they are electing, who is governor of Arizona?
I only comment on what I see from the trends.
No, however, it seems that the majority of “transplants” that I have met are Dems. Of course, this isn’t just from California...a lot of people from NY are moving here (at least more that I have seen before)...suffice it to say that it isn’t just because this state is half mexican, it is because it is being invaded by city dwellers.
