Cato: "The evidence indicates that, on balance, the oil industry is not a net beneficiary of government subsidies... The contention that oil consumers do not pay their fair share of the environmental and national defense costs they impose on society is dubious. There is little evidence to suggest that the environmental externalities imposed by oil consumption exceed the taxes and regulatory costs paid by consumers."
That's about as close as anyone has ever come to fully-backing oil subsidies. They're not terribly popular in normal political discourse. The piece unveils a dubious argument that evades the fact that taxes on oil are used to finance the cost of roads and highways. They do not serve to mitigate national defense costs, environmental damages, or health costs caused by burning fossil fuels, extracting them, or refining them. These costs are borne mostly as hidden externalities paid by government and consumers.
