I wonder why Hillary Clinton Doesn't look worried

Her opponent, KT McFarland, when arguing that her husband (Bill you know) was responsible for 9/11 said "

McFARLAND: Tell that to 2,000 people who died.

OK she didn't say "tell that to the 2,000 people who died on September 10th 2002 while Bill Clinton was president," but I think she did as much as is humanly possible to help the Clinton campaign.

I know numbers can be tricky things but I wonder if 2,000 New Yorkers are going to vote for this McFarland person.
