Sen. Bill Nelson (D) leads Gov. Rick Scott (R) in a new poll from Quinnipiac poll, 52% to 47%. Nelson has trailed Scott for most of the summer and fall. Scott, a two-term governor who is term-limited, has spent millions of his own fortune to fund his campaign. Nelson may be benefiting from the popularity of Mayor Andrew Gillum, the Democratic nominee for governor. Nelson has consistently been ranked among the most endangered Democrats up for reelection in this cycle.
