I envision him picking a running mate with Latino appeal. Perhaps Rubio, although I doubt he'd accept. But Florida is a must win for Trump in the general election, and he cannot carry the state without some sizable part of the Hispanic vote. Hillary needs to shore up her support among the liberal wing of the Democratic Party, as well as bolster her support in the Midwest --- the only place I see has having where Trump can make any inroads from previous Republican presidential candidates. Sherrod Brown would help her in both of these spheres. Note: Won't allow me to edit the previous message for some reason.
