The post correctly notes that undocumented immigrants are counted in the census and that House seats are apportioned by total population. However, it significantly overstates the partisan impact: peer-reviewed research and multiple analyses show that excluding undocumented immigrants from apportionment would shift at most 2–5 House seats between parties in any given census cycle, and this has never changed party control of the House.

Undocumented immigrants settle in predominantly liberal counties and cities.Partially true but oversimplified. While many undocumented immigrants live in blue states like California and New York, large populations also reside in Texas and Florida, which are Republican-led states. The geographic distribution is more mixed than the post implies.
-
Undocumented immigrants are counted in the census for House apportionment.True. The Constitution requires apportionment based on 'the whole number of persons in each state,' and this has consistently been interpreted to include all residents regardless of immigration status.
-
House of Representatives seats are based on population.True. The 435 House seats are reapportioned every decade based on total state population from the decennial census.

Counting undocumented immigrants in the census results in a greater number of liberals in the House than if they were not counted.Misleading in magnitude. A peer-reviewed study (Warren, analyzing 1980–2020 censuses) found that excluding undocumented residents would shift no more than 2 House seats between parties in any year, with no impact on party control of the House. Pew Research projected similar minimal shifts for 2020. The Center for Immigration Studies also notes that apportionment shifts from immigration are driven primarily by legal immigrants (~75% of the foreign-born counted), not undocumented immigrants. The post implies a substantial partisan advantage, which research does not support.
Caveats
Estimates of the exact number of seats affected vary slightly by study and methodology (ranging from 2 to 5 seats), but all credible analyses agree the effect is too small to alter party control of the House. The post does not specify a magnitude, so the degree of misleadingness depends on how a reader interprets 'affecting the results of an election.'
Community note
Misleading. While undocumented immigrants are counted in the census and House seats are based on total population, research shows the partisan impact is minimal. Excluding them would shift at most 2 to 5 seats, never changing party control. Large populations also reside in Republican states.
