I begin with some broad observations on the concept of political feasibility. To begin: this concept is nested within some broader ideas of possibility, some of which are outside the domain of politics. For example, if a policy proposal is logically or mathematically impossible (as many covertly are), then it cannot be politically feasible. Similarly infeasible are policies that contradict well-established natural scientific laws—the bizarre episode of Lysenkoist agriculture during Stalin’s regime, for example. Nor can an option pass the test of political feasibility if it violates key Wndings from other social sciences such as economics or psychology
