Biggest mistakes
- The big-state strategy - a caucus or two in the west would have made a lot of difference
It's not a strategy, it's an excuse.
As to what she should have done differently...
I'll agree that she should not have contested Iowa. That was always the only state in contention throughout 2007. Yes, it could have given Edwards a chance, but she'd have defeated Edwards (& would easily have won a 3-way race, I think) later on.
Obama was running ads in VA & MD before February 5th. He knew what he was doing. Yes, he had more money, but it doesn't excuse her failure there.
Her delegate deficit is almost entirely due to caucus failures. If she had performed respectably there, that's 100 delegates she could have made up. If she had tried in February, they'd probably be tied right now.
