Why Edwards Should be Heavily Favored in Iowa
The Democratic precinct caucuses begin with a division of caucus-goers by candidate. Each camp then bargains with their neighbors to bring them over, until finally everyone stops and the numbers are tallied.
Then, if any of the candidates do not reach the 15 percent threshold, their supporters can either leave or move to another candidate, their second choice.
With that in mind, consider the fact that John Edwards is the second choice of 42 percent of likely Democratic caucus-goers.
