How the Iowa Caucuses Work
Remember, what happens tonight in Iowa is a caucus, not a primary. Thus, participants are not "voters." They are, well, caucus participants. Or caucus attendees. David Yepsen, Des Moines Register columnist, calls them "caucusgoers" ... athough other Register political reporters continue to call them "voters." But, at least on the Democratic side, they are not "voting." Got that?
A lot of questions also center on the words "viable" and "viability." This is more about Democrats. It will be easy to calculate how the Republican candidates do, since the GOP contest in Iowa is basically a "straw poll," where Republican caucusgoers simply show up at a caucus site and cast a presidential preference ballot.
For Democrats, it's showing up for hours at a time, discussing issues like Iraq and ethanol, and then, when it comes time to declare presidential preference, standing in part of the room along with like-minded people. But if a candidate in a precinct fails to attract the support of 15 percent of those attending (smaller precincts require a larger threshold), that candidate is not considered "viable."
Thus, that candidate's supporters have the option of joining up with another candidate, or simply going home. In any event, those final tallies are what the Democrats release, not the total number of folks who show up on behalf of each candidate.
