Abzug was an extreme Lefty representing Manhattan’s “Silk stocking district” and as you pointed out was of Jewish heritage. Mrs. Carter appeared with Abzug at the big “Women on the Move” fest in Texas. Betty Ford was also there. The agenda was largely a pro-abortion one.
Nellie Gray was the leader of the annual March for Life in Washington each winter and was thus the opposite of Mrs. Carter.
Abortion is an example of how Carter played the religion game with the American public and why Christians came to question his authenticity.

Abortion
“Although Carter was personally opposed to abortion, he supported legalized abortion after the landmark U.S. Supreme Court decision Roe v. Wade, 410 US 113 (1973).[2] Early in his term as governor, Carter had strongly supported family planning programs including abortion to save the life of a woman, birth defects, or in other extreme circumstances. Years later, he had written the foreword to a book, Women in Need, that favored a woman’s right to abortion. He had given private encouragement to the plaintiffs in a lawsuit, Doe v. Bolton, filed against the state of Georgia to overturn its abortion laws.[3] As president, he did not support increased federal funding for abortion services. He was criticized by the American Civil Liberties Union for not doing enough to find alternatives.[4]
In a March 29, 2012, interview with Laura Ingraham, Carter expressed his wish to see the Democratic Party becoming more anti-abortion, allowing it only in the case of rape, incest or risk of maternal death.”
