Money quote:

Endorsing Trump gets Palin back into the spotlight, increases Trump’s bona fides with lots of conservatives and blue collar voters, and as Glenn noted yesterday, is a way for her to stick it to the GOPe, who never had her back in the fall of 2008 and afterwards. And it’s possibly a ticket to a cabinet position as well. This doesn’t exactly require complex rocket surgery to parse out.

Bottom line, we get the government we deserve.
