NBC's exit poll didn't ask where voters were born, so no 2026 data shows how newcomers voted. In 2024, Texans born elsewhere did lean less Republican than natives, splitting about evenly.
NBC's exit poll this year didn't ask where voters were born. In 2024, Texans born elsewhere split 50% for Trump to 49% for Harris, while natives backed Trump 60% to 38%10. In 2018, newcomers were the more Republican group11. Neither poll separates immigrants from people who moved from other states.
Timing cuts against the idea. Net migration from other states added 470,702 people from April 2020 to July 2022, by our sum of Census estimates, and that November Abbott won by 883,443 votes12,13. Net figures understate the churn: in 2024 alone about 556,000 people moved in from other states and 483,000 left14. Net international migration added about 1 million from April 2020 to July 2025, most of it after 2022, and noncitizens can't vote12.
The exit poll does show switching. Ten percent of Trump's 2024 voters backed Hinojosa. Voters who sat out 2024, 8% of this year's electorate, backed her 76% to 20%2. Some of them are newcomers. The poll can't say how many.
