MIAMI (AP) — From Pennsylvania to Florida to Texas, areas with high numbers of Hispanics often had little in common on Election Day other than backing Republican Donald Trump over Democrat Kamala Harris for president.

Trump, the president-elect, made inroads in heavily Puerto Rican areas of eastern Pennsylvania where the vice president spent the last full day of her campaign. Trump turned South Texas’ Rio Grande Valley, a decadeslong Democratic stronghold populated both by newer immigrants and Tejanos who trace their roots in the state for several generations.

He also improved his standing with Hispanic voters along Florida’s Interstate 4 corridor linking the Tampa Bay area — home to people of Cuban, Venezuelan, Nicaraguan, Colombian and Puerto Rican origin — with Orlando, where Puerto Ricans make up about 43% of the local Hispanic population. Trump was the first Republican since 1988 to win Miami-Dade County, home to a sizable Cuban population and the country’s metropolitan area with the highest share of immigrants.

It was a realignment that, if it sticks, could change American politics.

Texas and Florida are already reliably Republican, but more Hispanics turning away from Democrats in future presidential races could further dent the party’s “blue wall” of Pennsylvania, Michigan and Wisconsin, that had helped catapult it to the White House before Trump romped through all three this time. The shift might even make it harder for Democrats to win in the West, in states such as Arizona and Nevada.

Harris tried to highlight the ways Trump may have insulted or threatened Latinos.

Trump, in his first term, curtailed the use of Temporary Protected Status, which Democratic President Joe Biden extended to thousands of Venezuelans, and tried to terminate the Obama-era Deferred Action for Childhood Arrivals program. He also delayed the release of relief aid to Puerto Rico after Hurricane Maria in 2017 until nearly the end of his term, having long blasted the island’s officials as corrupt and inept.

Once he returns to the White House, Trump has pledge to stage the largest deportation operation in U.S. history. That could affect millions of families in mixed-status homes, where people who are in the United States illegally live with American citizens or those with legal residency.

But the Democratic warnings did not appear to break through with enough voters for Harris. Now the party must figure out how to win back votes from a critical, fast-growing group.
