Donald Trump isn't backing a national abortion ban. That's not hurting him in the GOP primary

Donald Trump has refused to endorse a federal ban on abortion, allowing some of his rivals to get to the right of him.

The tension underscores the new reality the GOP finds itself in more than a year into the post-Roe era.

The dynamic will be on fresh display in the coming days , at events dominated by social conservatives.

Many in the Republican primary field have taken a harder line on abortion.

The country’s leading anti-abortion group, Susan B. Anthony Pro-Life America , wants GOP presidential candidates to advocate for a 15-week federal ban.

Other major candidates have been noncommittal on national bans in favor of state restrictions.
