Florida from purple to blue

ST.Petersburg Florida once a republican stronghold due to its large senior population has swung democratic.First with the the first Democratic mayor elected since 1975.Next a democrat running for U.S. congress in that area is ahead in the polls.Why is this happening?Changing demographics that are also happening in other areas of Florida.A large flex of Hispanics and African Americans of voting age have emerged.Also thanks to expansion of the silicon valley generation young urban professionals are now moving to Florida.This is especially true in areas like Orlando another former GOP area,that has a democratic mayor and one of the most liberal members in Congress Allen Grayson. RIGHT ON.GOP your stranglehold is dissolving.
