Sarah endorsed Trump on the 19th of January. The grandmother died on the 20th of January. The Palin's returned to Alaska, because the grandmother was on her death bed. The media's meme was to tar the Palin's with their son's behavior by reporting that the Palin's left the campaign trail because of Track.

Here's the obituary.

I'm sure I can spend a few minutes and find out when Track was arrested. Personally, I don't care when he was arrested.
I cared enough about my grandmother to sleep in her hospital room and I heard her draw her last breath. I woke my aunt who was asleep on a cot, upon realizing that my grandmother had just died. She had six other children (adults) that were not there at the time. My point being that my grandmother was important enough to me, for me to be at her side until she slipped the surly bonds of earth. I'm betting Todd Palin's grandmother was as important to him, as mine was to me, so that is why the Palin's returned to Alaska, in such haste, not because of their disturbed son's behavior.
