The fast-growing I-4 corridor area, which runs through Central Florida and connects the cities of Daytona Beach, Orlando, and Tampa/St. Petersburg, has had a fairly even breakdown of Republican and Democratic voters. The area is often seen as a merging point of the conservative northern portion of the state and the liberal southern portion, making it the biggest swing area in the state. Since the late 20th century, the voting results in this area, containing 40% of Florida voters, has often determined who will win the state of Florida in presidential elections.
