Seems to me she’s just following Barry’s lead; I seem to recall that he counted people differently himself:

OBAMA: 10,000 People Died in Kansas Tornado.

“In case you missed it, this week, there was a tragedy in Kansas. Ten thousand people died — an entire town destroyed,” the Democratic presidential candidate said in a speech to 500 people packed into a sweltering Richmond art studio for a fundraiser.

Guess they just count differently, that’s all.
