Rabbit,
This is not so much a projection of how they will turn out as how they WOULD or COULD LIKELY turnout if there was no change to current candidate momentum and/or voter sentiment.
Or at least that is the way I take it.
Gotcha. Like I said, it was an interesting read and does show the increased likelihood of a brokered convention — especially, as you point out, if we take things as they currently stand.
Carry on!
