TALLAHASSEE — The once-a-decade process of redrawing the  state's political lines has left a big footprint on the First Coast.

The area is left with its first open congressional seats — two, to be exact — since U.S. Rep. Ander Crenshaw replaced Tillie Fowler in 2000, competitive state  Senate races, Clay County with entirely new representation in Tallahassee and  Duval County with a smaller presence in the state Capitol.

The new maps mean a rare occurrence for First Coast voters: a competitive  election cycle.

"Northeast Florida has always been good to incumbents at all levels of  government," said state Rep. Mike Weinstein, R-Jacksonville. "In the past, there  has not been as much disruption in our area of the state."

As an example of this year's disruption, Weinstein has decided to run for state Senate after being  drawn into a House district with state Rep. Charles McBurney,  R-Jacksonville.

Now that the new maps officially have the Supreme Court's  blessing, here are some of the biggest changes to the First Coast's political  lines.

Congress Open congressional seats are a big deal.

With no term limits, it's not often that an incumbent-free district emerges.  The area's current congressional delegation is evidence: In addition to  Crenshaw, there's Cliff Stearns (elected in 1988), Corrine Brown (1992), and  John Mica (1992).

Both of Northeast Florida's open congressional seats are newly drawn.  District 3 extends from the Gulf of Mexico to Clay County, and District 6 is a  coastal seat that includes St. Johns, Volusia, Flagler, and Putnam  counties.
