The Nevada Caucus

The Nevada Caucus style of primary voting. Other than a name I can't say without giggling like a 5 year old boy. Then I just burst into laughter when they mention President Bush in the same sentence. Is the town meeting style of voting effective? Or is it just a silly.

How is a caucus different from a primary election?
In a primary election, voters use a secret ballot to select their preferred candidate and the votes are tallied similar to a general election. Caucuses are public meetings, where Democrats make public declarations of support and can argue with one another over who would be the best nominee.
