No, it's not a poison pill. All Dreamers, especially the ones who have lived here the longest, gone to school, worked, and now have families SHOULD be included.
There were no poison pills on last week's debate. Each side was getting something they wanted.
Btw, the Washington Post has a report today about Melania Trump sponsoring her parents thanks to 'chain migration'. The White House considers not banning relatives from migrating legally a 'poison pill'. What a bunch of hypocrites.
