It's easier to understand why the Clinton campaign would rather plant their questions than answer them.
He's still not where some of his supporters would like him to be.
If they can upset Hillary Clinton, and win in Iowa, that really will help them propel them to the next stop, which is New Hampshire.
It's sort of unnatural for him to be directly attacking a fellow Democrat.
