An example of the huge disparity on illegal immigration viewpoints between House Democrats and Republicans:

STRIVE Act: HR 1645
Sponsors:
65 Democrats
8 Republicans

Birthright Citizenship Act: HR 1940
Sponsors:
1 Democrat
90 Republicans

This pretty much speaks for itself, but:

Basically, I think we all know, that for the most part, simply put...Democrats favor providing services to illegal aliens and getting them legalized, Republicans (for the most part), favor the opposite.
