Here´s an alternative map showing "safe" Clinton and Giuliani states as of now and possible battleground states (candidate leads by less than, or exactly 5%):
I included only polls which were conducted in June/July/August, therefore RI, NV, CT and WV have been removed.
OR, MN, FL and NH are leaning towards Clinton, because no poll has shown Giuliani ahead there in recent months and a Clinton lead is also supported by other polls in the state.
I don´t know about MO, KY, VA and NC so far, we have to wait for other polls to see if they are really swing-states next year.
That leaves WI, OH, PA and NJ as the ultimate swing-states so far.
