New Castle County is one such example. The county sent both Democrats and Republicans to the House over the last 10 years. Though Rep. John Carney, a Democrat, now occupies the seat, Republican Michael Castle preceded him, serving his final term in the 111th congress.

Gadsden County, for example, sent both Democrats and Republicans to the House over the last 10 years. Rep. Gwen Graham, a Democrat, now occupies the seat. Marco Rubio, a candidate for the Republican presidential nomination, represents the Sunshine State in the U.S. Senate.
