DES MOINES -- Ok, they took a count (by playground rules: raising hands and counting off.) The official count is 554. What that means is a candidate needs 83 people to be "viable."
Now they've formed into groups. Obama, Clinton and Edwards' supporters -- the largest -- in gthe bleachers. The second-tier candidate groups oare on the floor. And they're counting off again. If somebody fails to make the magic 83, the horse-trading begins.
In 2004, John Kerry led after the first count. Then, after supporters of the non-viable candidates went elsewhere, Edwards ended up winning.
