I don't think Google should censor their search results to get on the good side of a politician. Google's mission is to organize information, not to satisfy lawmakers.
Another example to read the comment fully:
"This isn't a plea to treat all potential presidents with kid gloves, it's a plea to make sure that pranks against public figures of all kinds are squashed once they become known."
Organising information is one thing - allowing pranksters to prank public figures is something else.
We might all laugh because we don't share the targets politics - but one day it will happen to someone we do support or care about.
