Contrary to belief of many conservatives, California is not a state of "latte liberals."
I always thought that this blanket statement was a little ridiculous. The dynamic has changed slightly and since the Dem's have secured some large money donors. IE) Soros. These types of comments can hold a little water. I don't think that most Dem's would identify with that analogy. (I do enjoy a good coffee house drink though) The traditional Democratic constituents are blue collar workers and are still a strong base. IE) steel workers, UAW, sheet metal workers, etc......If you ever spent a few days on a construction site, I think you would agree that many wouldn't identify with "latte liberals".
Urban vs. Rural is an interesting phenomenon as well. It's kind of like which religion you were born into. You typically follow that path.
