Three weeks after leaving the Florida Senate because of term limits, Lauren Book is running to return to Tallahassee. “Quite simply, my work is not done,” Book said in a statement Tuesday morning. “Residents deserve bipartisan solutions to the real problems our communities face, and as one of the most effective Democratic members of the Florida Senate in recent history, I have a proven track record of working across the aisle to achieve meaningful results.” Book, a Broward Democrat, filed paperwork on Monday to run for a different state Senate seat than the one she vacated. The move has been the subject of discussion among political insiders, and was expected.
