Congressional elections work much differently than presidential elections. My vague impression is that nuts-and-bolts level concerns like what industries go in what state are handled by Congress, not the president.

No, actually, the federal government doesn't do all that much to determine what industries go into which states. Mostly its private decision making. Businesses are generally free to locate their operations or management wherever they want to. Of course, some businesses, like gambling, are illegal in some localities or they can get more favorable treatment in certain locations rather than others, but typically the federal government doesn't make those decisions.
