Maybe she needs to realize that there are some things bigger than family.
I think that the Trump camp made too much of a fanfare of her endorsement; a tactical error, albeit probably small.
Palin appeared in AMES, Iowa, then went to Tulsa, Oklahoma to appear with Trump.
After AMES, and before TULSA, the media claims she was supposed to be in NORWALK, Iowa and didn't show (because she had to go home and take care of her elder son).
I didn't know that ALASKA was in between IOWA and OKLAHOMA.
