Looks to me like the biggest group he may have lost were Souvrn' whites and the rest of the Nawthan' blacks.
Hmm ~ maybe Jesse Jackson could tell us about that.
And don't be using any numbers from those sites that cite the Annenberg research and statistics ~ that Foundation was long ago taken over by its leftwingtard staff. Virtually nothing they say is worth looking at. BTW, almost all the reports in the first thousand or so references get back to Annenberg. Look deeper.
To save time, just make it real simple and tell us how, when LBJ won with more than 61% of the vote, and won 59% of the white vote, you think that he won by doing better among blacks.
