The irony: As of right now, Wal-Mart is one of the leading sellers of firearms and ammunition, if not the leading seller, in the country.
The goal: Obama wants to end private gun sales, period. Not just "close the gun show loophole" -- which is a bogus argument to begin with -- but to end private sales between a father and son, a mother and a daughter, two neighbors, two hunting buddies, etc.
To do this, he is leveraging Wal-Mart by showing them how they will benefit from supporting his push to cut off other avenues of gun sales. If effect, he's saying support this and more people will have to come to Wal-Mart to get their guns.
What he's not telling them is that he has to greatly reduce Americans' freedoms to do it.
Gun-grabbers have wanted to end private gun sales for decades -- not because doing so makes anyone safer (it doesn't) nor because it will prevent another Sandy Hook (it won't). Rather, they have always wanted to end private gun sales because that will force all gun buys and sales to be recorded on paper with the government, which will begin to provide ade facto gun registry.
Wal-Mart is a great retailer, an emblem of the American dream come true. However, shame on them if they put the almighty dollar before liberty and sign on to Obama's gun control nightmare.
