I'm willing to bet your right. Budweiser is a big piece of Americana and seen as the man's man beer. Especially in the geographic region you mentioned.
On a similar note; the region I am from, the North East, highly values PMW above all else in life. If someone came in and said something lame like "family" or "education" is going to replace P, M or W well... then I will move to an area where my values are accepted.
This logic can be applied to the InBev buyout of Budweiser as many steadfast American alcoholics will be forced to now drink Coors as Coors is the closest thing to the popularity of product that is Budweiser. Some Americans now have no choice but to drink Coors or else they will burst into flames much like the Tony Stewart fan would if he were to walk into Lowes as you had mentioned.
I'm buying stock in Coors.
