A Phoenix-based market research firm has released results from a poll showing Arizona voters not only think drug prices are higher in the U.S. than the international average, they also want Congress to do something about it. 

An AARP-commissioned poll from OH Predictive Insights found almost unanimous support to allow Medicare to negotiate the prices of prescription drugs. 

The poll of 800 registered voters revealed about two-thirds of voters showed concern about the cost of drugs. 

While about a third of all respondents have decided not to fill a prescription from a doctor, nearly half of Hispanic or Latino voters in Arizona have skipped filling a prescription. 

OH Predictive Insights’ chief of research Mike Noble says Congress would get more support if they took action to lower drug prices. 

“Even Congress members of a voters differing political party who take action to lower drug prices would still enjoy the support of 59% of Arizona’s voters," Noble said. 

The poll was conducted in an online survey in late September from a statewide registered voter sample.
