Nate Silver: "These are not the hallmarks of a race with a dominant candidate. Nor,
even, of a race with a candidate like John Kerry, the best of a somewhat
weak lot of Democrats in 2004, but one whom the party settled upon
fairly quickly. Instead, this race bears more resemblance to something
like the 1984 Democratic contest or the 1976 Republican race. There was a
favorite in each of those contests -- Walter Mondale in 1984 and Gerald
Ford in 1976 -- and they were ahead in the delegate count more or less
from start to finish. But both contests progressed through all 50 states
and were not that far from going to the convention."
