The pejorative term 'crackers' is sometimes used to accuse people of being white.
1/31/12, "Politico's Jonathan Martin Mocks Conservative Florida Voters as the 'Cracker Counties'," NewsBusters, Scott Whitlock
"Politico reporter Jonathan Martin on Tuesday mocked the "cracker counties" of Florida's conservative Panhandle. Talking to Daily Rundown host Chuck Todd, he derided, "Chuck, a lot of the counties in the Panhandle, in north Florida, the cracker counties, if you will...more resemble Georgia and Alabama than they do Florida." [See video below. MP3 audio here.]
MSNBC anchor Chuck Todd appeared indifferent to this attack, agreeing, "right." That area of Florida, of course, is where fellow MSNBC host Joe Scarborough represented when he was a member of Congress. No word yet on how Scarborough has reacted."...via Mark Levin
