You should have been paying more attention then. People have been saying this very same thing about caucuses for years. I continue to doubt that Howard Dean would have come in third in an Iowa primary.
It has nothing to do with Hillary Clinton or with Barack Obama. It has to do with an inherently unfair process that can't be scrutinized because of it's very nature. No one expected Hillary Clinton to win any of these caucuses - it's entirely irrelevant.
I notice that of all the posts I've read about caucuses, not a single Obama supporter has been able to rebut the objections that we are making. All you have is exactly what you wrote:
Hmmm.. Didn't hear a lot of people complaining about Caucuses before Clinton started loosing all of them.
There are rules that apply to primaries that clearly don't in a caucus. You can't have supporters of Candidate X cheering, jeering and intimidating other voters in the election, with good reason. But that's exactly what a caucus is.
Here's a news flash for you: there will be no caucuses in November. If Barack Obama is the nominee, that means trouble. His supporters won't be able to silence McCain voters by cheering and jeering.
