dem change 12-16 = +3,186
repub change 12-16 = + 5,382
net gain in repub favor = + 2,196
since obammy won this county by 1% in 2012
consider 100% voter turn out for dems 73,620 x .01 = +736
net gain by repub 12-16 = 2,196 - 736 = st lucie county should go repub by +1,460 votes this year if all the new repubs vote.
