Considering that Miami-Dade County is home to the most expensive real estate in the entire state of Florida (with Condo and housing prices that have skyrocketed over the past five years) be careful painting with such a broad brush. Besides, its the only county in South Florida that sends Republicans to the state house. Jeb won Miami-Dade County twice, something that can't be said of neighboring Broward or Palm Beach.
Its the only place I would live in Florida were I to move back (my parents live in the liberal hell hole of Boca Raton).
