TPM notes this and doesn't go on to explicity state it, altough that they understand it is clear, but the subtext here is racial.
When your average southern conservative republican imagines poor people, he sees black. And he does see them in almost precisly and literally these terms: as pests, animals, locusts, and so on.
You may think I am being too harsh here, but if there is one thing that history has taught us is that the white population of the south will go exceedingly out of its way to maintain blacks as second class citizens both legally and conceptually.
In many ways, the conservative world view is colored, from start to finish, from the offshoots of racism.
