"I expect if it did go through Bosch would keep most of Whirlpool's US manufacturing facilities"
That rarely happens these days. A good portion is sold off for big money (particularly real-estate) and either merged with another facility or sent overseas.
After Whirlpool bought Kitchenaid, it closed down all of their facility a couple of years later in 1988. When they acquired Maytag, they sold off Hoover and TTI. In 2007, they closed plants in Newton, Iowa, Searcy, Arkansas, and Herrin, Illinois, resulting in the loss of 4,500 jobs. The following year, they closed down plants in La Vergne, Tennessee, Reynosa, Mexico, Oxford, Mississippi, and Jackson, Tennessee.
