You're either just really not that bright, or completely and wilfully dishonest. I think it's probably a bit of both.
From your linked article:
Walmart is closing 154 stores. 102 of these are experimental "walmart express" stores, because they discovered (shocking) that people don't want to go to a walmart with a quarter of the stuff for "convenience" when there's a full sized walmart open 24 hours down the road. Almost all of the remaining 52 stores are in areas that are already well serviced by an existing walmart.
In addition to this (still on the same article that YOU linked as proof), within this year, they intend to open 50 to 60 new supercenters, 85 to 95 neighborhood markets, and 7 to 10 sams clubs, as well as expanding their online sales. I know that math isn't in your wheelhouse, but this is a net GAIN in stores, and therefore jobs.
Walmart closes down stores and reopens new ones all the time, dickhead. If you're blaming Obama personally for the stores that are closing, then he must also get the credit for the ones that are opening.
