Washington — Is the death penalty in America gradually dying?

There have been just two executions since May 1 and the total for 2016 probably will hit a 25-year low.

Execution drug shortages, sometimes grotesque errors in death chambers and legal challenges to sentences imposed by judges have contributed to a dramatic decline in the number of states that are carrying out executions.

Just three states, Texas, Georgia and Missouri, are using the death penalty with any regularity, though Texas has not executed anyone since April. Four executions are scheduled in the state before the end of the year.

The reduction in executions and in the number of states that are enforcing death sentences recently led Supreme Court Justice Ruth Bader Ginsburg to conclude, “I think the death penalty is fading away.” There is not enough support on the court to abolish capital punishment, Ginsburg said, but added that may not be necessary.

“Most states don’t have any executions. The executions that we have are very heavily concentrated in a few states and even a few counties within those states,” she said in a July interview with The Associated Press. Ginsburg joined a lengthy dissenting opinion by Justice Stephen Breyer last year, highlighting problems with the death penalty that led the two justices to conclude that it probably is unconstitutional.

States that have had to halt executions, though, are trying to figure out how to resume. Ohio and Oklahoma are among states that intend to resume executions once they have corrected well-publicized problems in their death chambers.

Ohio, which last executed an inmate in January 2014, has set a Jan. 12 execution date for a man convicted of raping and killing a 3-year-old girl in Akron, Ohio. But it’s unclear whether his execution, or more than two dozen others that are scheduled into 2020, will take place because the state lacks lethal execution drugs and has struggled to find a supplier, as have other states.

Oklahoma last execution was in January 2015, amid the use of the wrong drug and other problems. The state’s prison system is expected to adopt new execution procedures soon. Even then, Attorney General Scott Pruitt says he will wait at least another five months before asking a court to schedule an execution.

Alabama and Florida haven’t put anyone to death since January because of questions about the way death sentences are imposed in those states.

Even Texas has seen a reduction in executions.

So far there have been 15 executions this year. At the current pace, there would be 19 executions by the end of 2016, the fewest since 1991, when 14 people were put to death. The high-water mark was in 1999, when there were 98 executions.
