Journalists may make a politicized editorial decision by choosing to differentially retain (or even create) misspellings, mispronunciations, ungrammaticisms, dialect variants, or interjections.
In the context of a familiar word, listeners often ignored the mispronunciation altogether (a phenomenon later explored by researchers in the field of cognitive science).
One man moaned about his girlfriend's mispronunciation of the word "sandwich" while another told how his partner leaving the shower curtains open drove his berserk.
