(Radio Iowa) – Some demonstrators at weekend Iowa rallies expressed concern issues like same-sex marriage or contraception might be next to be revisited by the U-S Supreme Court, after last week’s rulings on guns and abortion. Iowa Senator Chuck Grassley doubts such issues would be reconsidered by the high court. “They’re not needed and I don’t expect that,” he says.

Grassley, a Republican, says there’s a clear difference between issues like abortion and birth control or L-G-B-T-Q rights. He says abortion has been the topic of debate for five decades — and longer. “Roe v. and Casey never settled anything in 50 years,” Grassley says. “It’s been a constant debate, where all these other speculations of what might come up have been long-term accepted by the American people, and none of them involves a life-or-death situation.”

In his concurring opinion issued Friday, Justice Clarence Thomas said the Supreme Court -should- reconsider opinions which protect same-sex relationships, marriage equality and access to contraceptives.
