Collin County's rapid suburban growth north of Dallas has compressed its presidential margins from R+28 in 2012 to R+11 in 2024, making it a closely watched indicator of how educated, high-income suburbs shift over time.

The shift began with civil rights. 1968 marked the realignment in Collin County, by a four points margin. The Republican margin reached its widest at sixty-three points in 1984. The 2024 margin was eleven points.

The political shift has tracked, in Collin County, the political shift of the South more broadly. A 54% non-Hispanic-white share, a median household income of $121,600, and a 6% poverty rate describe the demographic context. The county's voting pattern over the last decade is most similar to that of Douglas County and Delaware County.
