Prior to the amendment's defeat McCain blamed the pharmaceutical industry for pressuring the Senate to defeat the legislation.
"In a normal world this would probably require a voice vote, but what we're about to see is the incredible influence of the special interests, particularly pharma, here in Washington, that keeps people who cannot — that have to make a choice between eating and medicine," McCain said. "So what you're about to see is the reason for the cynicism that people have for the way we do things in Washington. Pharma, one of the most powerful lobbies in Washington, will exert its influence again at the expense of average, low income Americans who, again, will have to choose between medication and eating."
The vote came during a series of votes on amendments to a Food and Drug Administration reauthorization bill on Thursday. Thirty Republicans voted against the amendment.
Sen. Charles GrassleyChuck GrassleyHouse oversight asks for private meeting with EpiPen maker Grassley: Mylan not going far enough with EpiPen discounts Five things to know about the Clinton Foundation and its donors MORE (R-Iowa), a long-time supporter of allowing drug importation from Canada, spoke in favor of the McCain language Thursday morning.
"I have always considered drug importation a free-trade issue," Grassley said in his prepared remarks. "Imports create competition and keep domestic industry more responsive to consumers.
"If Americans could legally and safely access prescription drugs outside the United States, then drug companies will be forced to re-evaluate their pricing strategies," he added. "They'd no longer be able to gouge American consumers by making them pay more than their fair share of the high cost of research and development."
A border-state senator, Olympia Snowe (R-Maine), agreed that McCain's amendment would help reduce costs for Americans.
"American consumers are paying 50 percent higher costs for the same prescription drugs than Canadians do," she said. "We know for a fact that allowing drug importation generates considerable cost savings to the government, to individuals and businesses that provide health insurance coverage to their employees."
But Sen.

"We're not talking about bus trips of seniors to reputable pharmacies right across the border," Enzi said.
Enzi added that drugs from Canada would actually be from anywhere around the world, as Canadian pharmacies have acknowledged that they get most of their drugs from overseas.
"Drugs that supposedly come from Canada can really come from any place in the world and then are shipped from Canada," he said.
