Does a dem win in Arizona require that the Democrats win Maricopa? County?

[pbrower2a]

I see Maricopa County dominating Arizona politics even more than Cook County dominates Illinois politics. Arizona is unlikely to see any dispersal of its population. There might be relatively-pleasant places to live by a climatic standpoint, but those places are extremely mountainous. Construction, whether of buildings, water and sewer mains, or roads is difficult and expensive in mountains.  Greater Chicago in theory* can expand toward Rockford, Kankakee, and Bloomington without running into difficulties of water supply or land barriers (OK, it could expand into Indiana, Wisconsin, and even Michigan, but that would affect the politics of those states).  Greater Phoenix runs into mountains of stark relief to the north and east, and desert to the south and west.

The problem isn't the heat; it's a water supply. Give Phoenix an adequate water supply and it would be another Houston.

...Does anyone see Tucson becoming a giant urban area in its own right?

*It wouldn't be be practical, anyway. Greater Chicago depends heavily upon its location as a center of transportation for the rich farm product of the area and for industry related to coal from southern Illinois and limestone from the overall area for steel production. Greater Chicago probably maxed out on potential growth a couple decades ago, as budgetary problems of the State of Illinois demonstrate.
