In these polls, however, I think the way the question is worded can really affect the outcome... for example...
Do you think that police should have to report illegal aliens that they arrest for other crimes to the DHS to be sent back to Mexico?
-or-
Do you think it's okay for your local police department to be tied up doing paperwork and escorting countless undocumented immigrants throughout their shifts (which then conflicts with them doing their local policing duties) as well as your local jails being full of undocumented immigrants so that more dangerous criminals are free to act within the city unimpeded?
Which is what the public is not thinking about......
