Baffled?

Tons of interesting stuff in Patrick Healy's article on Hillary Clinton supporters reconciling themselves to probable defeat. This bit lurking near the end is, if true, pretty telling:

In interviews with 15 aides and advisers to Mrs. Clinton, not a single one expressed any regrets that they were not working for Mr. Obama. Indeed, some aides said they were baffled that a candidate who had been in the United States Senate for only three years and was a state lawmaker in Illinois before that was now outpacing a seasoned figure like Mrs. Clinton.

Whether or not you think the more "seasoned" candidate ought to win presidential elections, it seems to me that any campaign staffer who could be genuinely "baffled" by experience not proving to be a winning issue is demonstrating a scary ignorance of how things work. Is her staff baffled that Joe Biden didn't win the nomination?
