I don’t think that questioning Palin’s conservatism after her strange decision is heaping scorn.
We leave heaping scorn to the Trumpster.
I'll vote either Trump or Cruz so with that said, from what I've read since Palin's announcement (and even before), there was a ton of trash being thrown her way. The disappointed Cruz supporters went after her daughter for having two children by two different fathers. They went after her son's arrest. They went after her calling her a gold digger and making fun of her tv shows. One poster even hinted that she made money by participating in the world's oldest profession.
This has been way over the top and worthy only of David Letterman type attacks. It's been a lot more personal than just "questioning her conservatism"
