Beyond the actual security of the voting machines, the other challenge in any hack is making it match the demographic make up of a state. People talk about "red" and "blue" states but the reality is that states are not homogeneous. It would stand out if a traditionally red county suddenly went blue and vice versa.

You would never flip a county. You would increase the percentage your candidate wins by or the percentage of the population that voted. It's raw votes that matter in states, and it's much safer to set up in your home turf.
