The lawsuit phase of the Florida election recount has officially begun. While the national focus remains on the recount effort, particularly in Broward County, legal challenges from candidates and outside groups could alter the course of the race for US Senate, where .15 percent of the vote separates the candidates. As was the case 18 years ago in the 2000 Florida recount, there remains a possibility that the election could be determined in court rather than at local election offices.
