While he did not win the majority of the popular vote, he is claiming more delegates. However, here is a statement released today on Hillary's web site:
Clinton Campaign Statement on Nevada Victory
Hillary Clinton won the Nevada Caucuses today by winning a majority of the delegates at stake.
The Obama campaign is wrong. Delegates for the national convention will not be determined until April 19."
So, what's up? Here is a statement from what appears to be an official Nevada Democratic Caucus web site:
"Just like in Iowa, what was awarded today were delegates to the County Convention, of which Senator Clinton won the majority. No national convention delegates were awarded. That said, if the delegate preferences remain unchanged between now and April 2008, the calculations of national convention delegates being circulated by the Associated Press are correct. We look forward to our county and state conventions where we will choose the delegates for the nominee that Nevadans support."
So, it appears to me that Hillary is probably technically correct and that Obama may be jumping the gun a bit (but with some reasonable sense that this is how it will turn out in the end).
