How the Fight Over Abortion Rights Has Changed the Politics of South Texas

In the Laredo region, long a Democratic stronghold, that single issue appears to be driving the decision for many voters, the majority of whom are Catholic.

LAREDO, Texas — Like the majority of her neighbors in the heavily Latino community of Laredo, Angelica Garza has voted for Democrats for most of her adult life. Her longtime congressman, Henry Cuellar, with his moderate views and opposition to abortion, made it an easy choice, she said.

But as up-and-coming Democratic candidates in her patch of South Texas have leaned ever more liberal, Ms. Garza, a dedicated Catholic, cast a ballot for Donald Trump in 2016, primarily because of his anti-abortion views.

In choosing Mr. Trump that year and again in 2020, Ms. Garza joined a parade of Latino voters who are changing the political fabric of South Texas. In the Laredo region, where about nine out of 10 residents are Catholic, many registered voters appear to be driven largely by the single issue of abortion.
