With the US presidential election turning on a handful of swing states, suspicion arises that an incumbent could ‘buy’ the election by shifting the federal government’s state-level spending to critical states.

As such, it does not seem that Obama could buy votes in swing states such as Ohio using his power as the incumbent.
