Probably. A person usually gains popularity within their state/region before going national. Someone who cannot win their state is unlikely to gain national attention.
Add in the fact that having a president does tend to translate into many things moving to that state, and many "on the fence" otherwise might let that sway their vote to one side. I doubt it would convince anyone with strong opinions, though.

Only if you think all blacks have the same interests or even vote as a block, which they don't.
Also, while having a president hail from a state is going to provide some benefits. This is less about pure cronism and more to do with people tend to hire those they know, tend to have more ties to places they have lived and so forth. For example, whne Reagan was in office, B of A, then largely out west, got a big boost. Also, just the fact of having the "official residence" in a particular state can be a minor benefit.
However, you would have a hard time showing how race would have that same kind of impact, at least in modern times.
