This distasteful situation can, I think, be simplified by deleting the article altogether and if the original editor thinks there is anything about Santorum that he wants to say, let him say it in the biographical article with the same good taste that is required by Wikipedia editors instead of insulting the intelligence of everyone else into thinking that it is just an "example of the definition of neologism".  It is an ugly smear, nothing more, and inappropriate for Wikipedia.  It denigrates the entire project.  No deep discussion needed here in my opinion.
