I have my favorite theory why she blew this off. It is jumping out at me. Rather then opine I'll let people guess why she blew this off to see how much we agree.

[Gaffer]

She’s really not in control of her own faculties, IMO.

[Resolute Conservative]

Huma’s pregnant?

[sheik yerbouty]

Chronic, banged out, ethanolism, with the hangovers that come with it..

[Slings and Arrows]

It’s good to be Da Queen.

[Rational Thought]

Just a guess....Health issues.

After the debate last night, it appeared like she was having problems walking.

[Leaning Right]

Two equally-likely possibilities here, as I see it.

1. Some medical problem flared-up, forcing Hillary to cancel.
2. Good Morning America would not agree to some appearance condition of Hillary's, maybe like providing the questions in advance.

[EBH]

Illness is first guess. Debate was last night, right? Heard us was pretty rough. Alcohol abuse or stress related event.(another minor stroke) or both.

[SMARTY]

She CANNOT pass muster, unscripted! (And NOT scripted EITHER, for my money!)

[Gay State Conservative]

Ten bucks says that the “scheduling issue” was that she learned that the family of Ambassador Stevens was scheduled to be in the audience.

[IamConservative]

Hemorrhoids flared up? :)

[surrey]

She chose to stay in bed and snuggle with Bill and then a romantic breakfast of strawberries and champagne.

[blueunicorn6]

Hillary had another scheduling conflict with Jim Beam.

Hillary has health and stamina issues. He controls her campaign events so they are not stressful and she has not held a press conference since Decemebr. This is wher Trump will push her hard. He will go after her ability to handle the vigorous nature and energy required to be President.

[1Old Pro]

lack of stamina

[COBOL2Java]

She had a good debate performance. Who wouldn't want to cut loose and celebrate?

My guess? Huma found her this morning...

[seawolf101]

[BenLurkin]

She found out that she was NOT going to have control over what questions were to be asked.

[libstripper]

She had some kind of a moderate health crisis.

[Envisioning]

Live town hall? That’s rich. She might actually have to take unscripted questions. No chance....

[Robert357]

I really think that Hillary's health is very very fragile. Last night's screaming match debate with Sanders probably took so much out of her that she needs to rest and recover.

If she becomes the Democratic Party presidential candidate, she will never be able to go toe to toe with either Trump or Cruz in debates and campaign events.

If she becomes the nominee she will run a very low key and proxy campaign, where she just makes a few appearances, otherwise she will end up in the hospital.
