If I were Google's team I would kill this just because it looks very bad for Google. Let's assume Santorum goes on to win the Republican Primaries and then the Presidency.

It's the sort of thing that stays with people for a long time, rightly or wrongly.
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.
