I think 42% is too good for Sanders given how the demographic is. If we wins in Kansas, Maine, Nebraska & pulls an upset in Michigan, he will be going with a lot of momentum & can crack the 45-465 odd, essentially almost splitting the delegates.
Florida is not going to be easy for Sanders & of the March 15th States, I expect it to be the most pro-Clinton & it also has the highest delegates for March 15th.
But this is bad for Rubio, GOP is Winner take all, Rubio can't loose to Trump by 20% points, he has to win this or it is over for him. if Cruz comes with 200-250 more delegates than Rubio to the convention, there is a chance of him being a compromise candidate instead of Rubio
North Carolina will be worse for Sanders than Florida.
I think they'll be pretty close to each other. If Sanders spends some time in NC (Asheville, Chapel Hill, and Raleigh) I think could do pretty good in the mountains and Triangle area. I don't see any areas of equal strength in Florida (unless he surprises folks and does really well with the Jewish vote).
