A mistake means taking the other fork in the road would have been indisputably better.
Perhaps someone would be so good as to explain it.

1. Why Mrs. 'We came we saw he died' is what we want in a President
2. Why Mrs. got enough Democrats to support the invasion of Iraq and continued supporting it for 5 more years, is a good decision maker.
3. Why Mrs. we need a civil war in Syria is the person we need on the international scene
4. Why Mrs. Goldman Sachs would be great on the domestic scene
5. Why we know exactly what Mrs. has 'both a private and a public position on policy' really means when she hasn't been paid 225,000 dollars for the more candid opinion she gives to the banks.

It could be said the 'mistake' was the DNC for backing a neoconservative against a Republican candidate.
