What the Evidence Shows
The claim can be broken down into three main components: 1) Marjorie Taylor Greene introduced a bill requiring proof of citizenship to vote in federal elections, 2) the bill includes a new census counting only U.S. Citizens for apportionment purposes, and 3) this change is expected to cost Democrats 27 congressional seats by ensuring only citizens are counted.
First, it is accurate that Rep. Marjorie Taylor Greene has proposed legislation known as the "Making American Election Great Again Act," which would require proof of citizenship to vote in federal elections and mandate a new census that counts only U.S. Citizens rather than the total population.foxnews.comfoxnews.comRep.

Second, the bill’s provision to count only citizens in the census for congressional apportionment is highly controversial and widely regarded as unconstitutional by experts and legal analysts because the U.S. Constitution mandates counting the "whole number of persons" residing in each state, not just citizens.rawstory.comrawstory.com'Fatal flaw' dooms Marjorie Taylor Greene's citizenship proposal: expert

Third, the claim that this change would cost Democrats exactly 27 congressional seats is not supported by any credible evidence or authoritative analysis found in the search results. None of the sources provide data or expert projections quantifying seat losses tied directly to this bill. While it is plausible that excluding non-citizens from apportionment could shift some seats from states with larger non-citizen populations (which tend to lean Democratic) to states with fewer non-citizens (often Republican-leaning), precise seat counts like "27" appear speculative or politically motivated rather than based on rigorous demographic or electoral modeling.
In summary, while Greene’s bill does propose proof of citizenship for voting and a citizen-only census, the assertion about losing 27 Democratic seats is unsubstantiated and misleading. The constitutional challenges and lack of detailed impact analysis mean the claim overstates what can be reliably concluded about electoral consequences.
This verdict acknowledges the factual basis of the bill’s content but rejects the specific numerical prediction as unsupported by evidence.
