The article raises the question of what the criteria are for closing a dealership. If those criteria were known, then an informed assessment could be made on this debate.
The article also mentions another pertinent fact. Toyota, for example, limits the number of its dealerships in a given geographic area. This does increase the # of vehicles sold per dealership; and, thus, the profit per dealership. They also attempt to make their dealerships operate as "state of the art". Their service departments are quite good. My Toyota is 6 years old, and I still go to the dealer for service. Service is a big money-maker for the dealers as well.
I think the dealer closings criteria are important to know. If they are strictly performance-driven, then it could be that the partisan leanings of the owners are not the key factor. Some transparency would help.
Since BHO promised creation of 350,000 jobs ... he'll have to add an additional 100,000 (the jobs lost in the auto industry) to keep that promise.
It is also pertinent to mention that dealers saw the handwriting on the wall long before the rest of the population. Many of the GM and Chrysler dealers also incorporated foreign brands to their business. That has been going on for many years.
