According to [1] nytimes.com, in Spanish-language television commercials run by the McCain campaign:  “A male announcer says: ‘Obama and his allies in Congress say they are on the side of immigrants, but they’re not. Reports in the press say that their efforts were like ‘poison pills’ that caused immigration reform to fail. The results: ‘No’ to the guest workers program; ‘no’ to a path to citizenship, ‘no’ to secure borders. The reform didn’t pass. Is that being on our side? Obama and his Congressional allies — ready to block immigration reform, but not ready to govern.’”

Where McCain and Obama stand on immigration should be addressed in the debates.  However considering the state of the U.S. economy, immigration may be overshadowed by more pressing issues.
