Ever heard of conservative Southern Democrats?
Yevgeny Vilensky (Yale Free Press) takes Keith Olbermann (MSNBC) to task for these voter fraud insinuations of Olbermann's:
[T]he majority of the media has yet to touch[, among other things, the story of] . . . huge margins for Bush in Florida counties in which registered Democrats outnumber registered Republicans 2-1, places where the optical scanning of precinct totals seems to have turned results from perfect matches for the pro-Kerry exit poll data, to Bush sweeps.
Vilensky points out:
I decided to go to the Florida Secretary of State's office webpage and look at the results for Lafayette, Baker, and Liberty, the three counties whose names I could catch [on Olbermann's MSNBC broadcast], and see how they voted in 2000 and in 1996. Well, quite a fascinating result:

Election of 2000
Baker voted 5610-2392 for Bush against Gore.
Lafayette voted 1670-789 for Bush against Gore.
Liberty voted 1317-1017 for Bush against Gore.

Election of 1996
Baker voted 3684-2273 for Dole against Clinton
Lafayette voted 1126-899 for Dole against Clinton
Liberty voted 913-868 for Dole against Clinton
