During the period Hillary was on the Board, WalMart opened between 170 and 250 stores per year, not including an additional 25-50 Sam's Clubs. She would have had to have had her head in the sand not to know that plenty of people, including unions, were criticizing WalMart during this period for destroying local mom and pop stores.
For someone who would like to compete for John Edwards' supporters who represent the workers of America, it will be difficult for her to justify turning a blind eye to the treatment by WalMart of its employees and its disdain for the welfare of local businesses in the community. In fact, WalMart Attorney John Tate often referred to labor unions as "blood sucking parasites". This is one more example of the "flip-flop" behavior of Mrs. Clinton on this and many other issues such as Iraq, licenses for illegal immigrants, etc.
