The Post reports:
The mistake is a minor shift with major implications. The new projection now shows the Vermont senator winning 39 delegates in Colorado, compared to 27 for Clinton.
Even if Clinton wins all 12 superdelegates in the state, Sanders can finish no worse than a split decision. It contrasts with prior projections from the Post, Bloomberg Politics and The Associated Press that indicated Clinton would probably win the majority of the 78 delegates in Colorado because of her support from party leaders with superdelegate status.
If he lands one Colorado superdelegate — two are still undecided and others are facing significant pressure — Sanders could win the state's delegation.
