Not all of us are "ruining" those states. I grew up in California, but we were conservatives when we lived there and we are conservatives living in a conservative area of Arizona.
No offense intended, as obviously I wasn't referring to conservatives moving from Calif. to other states, but clearly there is a negative effect of the migration. The fact that the Dems are targeting AZ, NV, and CO indicate that they believe these red states have enough rot in them to swing them into their column.
