That’s the nature of government spending. At a point, almost anything could be considered partisan, but through representative democracy we choose representatives to spend in our interests, which are typically partisan. At least this is the case in a mainly two party system. Regardless, if spending attempted to avoid partisanship, it would go against the will of the people, as people will typically want some form of “partisan” action and/or spending. Although, there are issues with democratic voting and representation of the majority, in theory, there isn’t an issue of partisan spending in concept.
