It's always a modest achievement to find a significant copy editing mistake in the NYT

See if you can find the "their-there" mistake in the sentence below, from the NYT:

However boring, this show was a dramatic encapsulation of how a once-invincible candidate ended up in a dead heat, crippled by poll-tested corporate packaging that markets her as a synthetic product leeched of most human qualities.

Yep, it should say "leach", not "leech".

Maybe the copy editor was in a hurry...one would think this other sentence from the same article might have been improved on: "some in attendance appeared to trance out".
