Suspicious unsupported comments on liberal sites

I'm beginning to wonder whether the Republican presidential money machine is paying folks to post non-sense, ad hominem responses to articles on liberal web sites.

Case in point are comments (replete with egregious spelling errors) attached to a current article by George Lakoff and Elisabeth Wehling on the Common Dreams site.

Do these comments really come from regular readers of Common Dreams? I don't think so. So what brings them to Common Dreams? The Koch brothers?

If the comments made any sense at all, or addressed the issues raised in the article, they would have value. Instead they are vacuous rants devoid of any substance.
