I hate to say good things about Calvin Griffith, but I think that we Washington fans are wrong to equate Calvin Griffith and Bob Short. Racism was a factor in why Griffith moved, and also WHERE he moved, but in the end I am convinced that the number one reason Griffith moved was that he was losing money in DC and wanted to move somewhere to better provide for his family. Once the Senators became the Twins, he built up the Twin Cities into a baseball town(s). He also provided for former members of the Senators which is why some of the great players of the 20's or 30's are buried in Minnesota. He only sold the team once he stupidly made openly racist comments that turned public opinion in Minnesota against him.
Robert Short, on the other hand had as much long-term designs of baseball in Washington as he did in Dallas---none. I am convinced that his intention in buying the Senators was to move it to another city and then make a profit by selling the team at a higher price to a local bidder, because this is exactly what he did with the Minneapolis Lakers. Ironically, if Short had managed to put in the hard work and effort that subsequent owners like Jack Kent Cooke and Dr. Jerry Buss, he wouldn't have needed to buy/move/sell the Senators because he'd be making money hands over fist in La-La land. I have great respect for what SUBSEQUENT owners of the Rangers done in building up baseball interest in Dallas/Fort Worth but I have none for Short. If the American League had agreed to sell the Senators to Edward Bennett Williams instead, I'm convinced the team would never have moved and baseball history in this city would be significantly different.
I can't think of a Washington player from the '20s or '30s who is buried in Minnesota. Clark Griffith is buried in Lincoln Cemetery, which is, best I remember from long ago, is on the Anacostia. I assume Addie Griffith (wife of himself) is buried beside him. Even Calvin is buried there.
Many of those players settled in and around Washington. Walter Johnson bought a farm in Montgomery County...I think the house is still in the family. Joe Judge was baseball coach at Georgetown. Sam Rice owned a farm somewhere around Charles County (have to look that up). Bucky Harris is buried in Bethesda. Nick Altrock died in Washington but is buried in Ohio, where he grew up. Did some hunting: only player I found who is buried in Minnesota is Ossie Bluege, who might have been working for the team when Calvin moved them.
Could the Old Senators have made money in Washington? I think so. They drew well in 1960, with a 5th place team in a ballpark that had about 15,000 unobstructed seats. Maybe a few more if you add the bleachers. Bob Addie (or Shirley Povich) believed that the team would have drawn over a million in 1960 with a bigger stadium...something like DC Stadium. The Senators took a strong core of players to Minneapolis (Killebrew, Lemon, Allison, Mincher, Battey, Versalles, Pascual, Kaat...offhand) and DC would have gone nuts for the '65 pennant winners and the '67 contenders.
