I've been saying here ... er, on MTS ... for years that these misspellings and malapropisms are intentional, and serve as a way to feed their insatiable need to be publicly recognized as victims of "liberal elitism", or whatever, in order to strengthen the bond between the Republican cons and their hapless red-hatted marks. Glad to see practically everyone else has come around to that idea.
And yes, @djhutch: I too believe the strategy, if not always the output, emanated from overseas. And I think we all know which sea it came over from.
