With perfect timing, Hillary Clinton’s presidential campaign announced a proposal to impose federal price controls on prescription drugs the day after Turing Pharmaceuticals declared it was raising the price of Daraprim, a medicine to combat the “toxoplasmosis” parasite, from $13.50 to $750 per pill.

Politically, Clinton may be on to something: In an August poll conducted by the Kaiser Family Foundation nearly three quarters of respondents said prescription costs are “unreasonable.” Four in ten favored government regulation to keep costs down.
