If we are not sure why the store closings maybe we can ask Hillary she might still be able to get some insider information she was at one time on their board of directors I believe. I am not sure if she was pro union at the time.
She is the quintessential left of center elephant stuffed in a donkey suit. She married into a family that lived in (at the present) a Red State. She is much more than what a Blue Dog stands for. So much so, that she'd fit right in with any moderate Repub worth their salt ideology-wise.
She will pull her share of moderate Repubs (mostly women) away from the party that know of her bonafide corporate credentials while being crucified by the Tea Party nutjobs as a flaming liberal when she's really not. In this regard, the Tea Party whackos are actually doing her a favor without realizing it.
She has to stand on the pillars of the Democrat ideology and swear allegiance to it, all while paying homage to the corporatists stuffing her campaign chest via payoffs like free trade agreements.
In today's world, she is the Dem version of the compromise candidate (macro economics-wise) that Romney was to his party in the last election cycle.
So of course she knows exactly what Wally World is all about, but her political stripes compel her to fight the good Dem fight while giving the Koch's of the nation a wink and a nod, signaling her willingness to give them what really counts to them, while
not giving them bucket-loads of news-making frivilous things to keep the Dem base happy.
edit - Like Obama understands, due to the political power imbalance that exists today, the reality of it all dictates that for the Dems to get a little, they have to give a lot in return.
