The parties were half different and half the same in the mid-late 20th century. It wasn't until Reagan that the GOP was what we consider to be conservative. More and more retired seniors have been moving to Florida which includes seniors dependent on social security and Medicare. Another thing I'll add though is that southern Florida is light blue but not as blue as the country thinks it is. It's only about as blue as Connecticut, California, or even Illinois but not like Massachusetts or Vermont.
Obama did better in Broward than in Vermont. The only state more Democratic than Broward in 2012 was Hawaii.
Yes but I said southern Florida, not only Broward County.
