U.S. Rep. Ileana Ros-Lehtinen, Florida's longest-serving member of Congress and political godmother to Miami Republicans, is quitting Congress after nearly four decades in office, providing Democrats a prime opportunity to pick up a seat that heavily favors them. “There was no epiphany. There was no moment, nothing that has happened that I've said, “I've got to move on,’” Ros-Lehtinen told her hometown paper, The Miami Herald.
