abortion is emerging as a major campaign issue in the United States. Supreme Court of Arizona on Tuesday ruled applicable a law of 1864, which prohibits abortion from conception, except in the case where the mother is in mortal danger.

Rape and incest are not considered valid exceptions. Polls show that the majority of Americans support abortion, which weakens the conservative party at the polls. Even voters in Kansas, a state anchored to the right, recently supported the right to abortion in a referendum. But the threat of a major tightening exists. The Democrats are making abortion a strong argument in favor of the re-election of Joe Biden, so far left behind by Donald Trump in the polls, writes Julian Zelizer. The U.S. president is now exercising restraint, recalling that each state is free to legislate on the subject, he says. “The Arizona Supreme Court went too far in its decision on abortion,” he repeated Friday on his Truth Social network. The Arizona Legislature, dominated by Republicans, must “act as quickly as possible” to adopt a new law, he said.
