Terry McAuliffe, the millionaire businessman who ran unsuccessfully for Virginia governor this year, is negotiating with investors and a U.S. automaker to lure a factory to southern Virginia — raising speculation that the ambitious Democrat is not done with state politics. McAuliffe has talked with Gov. Timothy M. Kaine (D) to brief him about his plans, which are focused on luring thousands of jobs to a part of Virginia where unemployment is high. McAuliffe declined through a spokeswoman to comment on his efforts, but Kaine confirmed the meeting and said McAuliffe is in the “very preliminary” stages of trying to put together a deal involving a “green” automotive manufacturing plant.
