Why did Rudy Giuliani go no where during the primaries? ?

In my opinion it's because of how the primaries are done. The states that held their primaries earlier were mostly states that he wouldn't even be expected to do well in but by the time those primaries were over and states he had a chance in held theirs the momentum had shifted to McCain and Giuliani didn't have enough money to keep campaigning. My state has closed primaries so I don't vote in those since I don't vote along party lines.
