That is correct. So when polling is done, they use the term "likely voters".

But that doesn't change the percentage between the parties and independents much, if at all.

However, I read the Obama campaign has gotten behind some 'New Math' in order to declare victory this Tuesday, no less--in Iowa. Seriously.

""Senator Obama, our campaign and our supporters believe pledged delegates is the most legitimate metric for determining how this race has unfolded," wrote Obama campaign manager David Plouffe Wednesday in a memo to superdelegates."

So, now the Obama Math is all about Most Legitimate Metric.
