Wal-Mart is refusing to comment on reports that the company has decided to ax GOP consultant Terry Nelson for helping to produce the RNC's controversial "bimbo" ad. Wal-Mart hired Nelson last month to help with its new voter registration drive. After news broke that Nelson, who was political director for Bush-Cheney '04, was a key producer of "bimbo," Jesse Jackson and an anti-Wal-Mart union group yesterday demanded that the company fire Nelson to prove it doesn't tolerate racism. Today the Huffington Post claimed that Wal-Mart has decided to toss Nelson, a report which is also circulating in Tennessee political circles. In a phone interview, Election Central gave Wal-Mart spokesman Dave Tovar several chances to deny that Nelson was getting fired; each time, he declined to comment. Stay tuned.
