Pew Research Center tracks attitude toward immigration policy over time:

https://www.pewresearch.org/short-reads/2022/09/08/republicans-and-democrats-have-different-top-priorities-for-u-s-immigration-policy/ft_2022-09-08_immigration_04/

This market resolves to a percentage:

• The group of interest is those who identify as Republican or Lean Republican (as grouped in the graphic).

• The percentage of interest is those who say the issue is VERY important as a US policy goal. In the graphic, that's the darker portion of each bar, and excludes those who say it is only SOMEWHAT important.

• In 2022, for example, the percentage of US Republicans who prioritize increased security along the US-Mexico border was 72%, up from 70% in 2019.

This market resolves depending on a survey and report from Pew Research Center:

• The report must include survey data from 2025 or 2026.

• This market resolves N/A if no report is published before 6/1/2027.
