Great news! If Clinton is leading in a Mason Dixon Poll (the pollster of "lolol Romney's gonna win let's stop polling here"), then she's in great shape!
wrrrrrrrong.
Last Florida Poll by Mason-Dixon was in July 2012.
http://www.realclearpolitics.com/epolls/2012/president/fl/florida_romney_vs_obama-1883.html#pollsObama was ahead with +1% margin(which was same as final results of Florida)
Mason-Dixon* 7/9 - 7/11 800 LV 3.5 46 45 Obama +1
And as I said above, This time Mason-Dixon Poll
1) Overweighted Democrats, Underweighted Independent voters
2) They included Johnson, but not Jill Stein(which can make minus of Hillary's numbers at least -2%)
