As for your trope about illegal immigrants voting, the past two elections...and especially the 2020 election were among the most scrutinized in the country's history...over 60 court cases alleging voter fraud all proven false...e.g. 5,000 deceased persons in Georgia allegedly voted...there were 4...Oh, and in Nevada a man submitted his wife's ballot after she had passed away...he was a Republican for Trump.
Undocumented Immigrants are among the last to even think of voter fraud, since such scrutiny would shine a light on them and get them deported. Note also that the Immigrant community is hard working, and more law abiding than native born Americans...even DJT has hired them to work at his golf resorts...
