Try New York for starters. Cost of transport is not an issue for the Obama campaign, esp wrt OH.
And do you seriously believe that a voter ID law is gonna stop these people? It’s not that hard to get an ID or the required documentation.....
Also the closest area of NY to OH is the far upper northwest corner. Buffalo Niagara Falls area. That is two plus hours from Ohio. It is also passing through PA, which is now a swing state and as important, OR MORE SO, than OH. O’Bumbler loses PA he loses OH, MI, and probably WI and he loses outright in a landslide.
Most of Upstate NY is republican and NYC which dominates the state is 10 hours away. Furthermore, taking dems from upstate NY will cost them dearly in the congressional elections.
