They vote Democrat because the Democrats give them money, drivers licenses, and welfare benefits and that is why some protect illegal immigrants.
Grow up. A driver's license is not a passport or de facto evidence of citizenship. It is an ID, one which Identifies the holder as a non citizen. It also means the holder of the license has some driver training and understands the rules of the road.
As for welfare,
"The extent to which residents of the United States who are not U.S. citizens should be eligible for federally funded public aid has been a contentious issue since the 1990s. This issue meets at the intersection of two major policy areas: immigration policy and welfare policy. The eligibility of noncitizens for public assistance programs is based on a complex set of rules that are determined largely by the type of noncitizen in question and the nature of services being offered. Over the past 18 years, Congress has enacted significant changes in U.S. immigration policy and welfare policy. Congress has exercised oversight of revisions made by the 1996 welfare reform law (the Personal Responsibility and Work Opportunity Reconciliation Act, P.L. 104-193)—including the rules governing noncitizen eligibility for public assistance that it established—and legislation covering programs with major restrictions on noncitizens’ eligibility (e.g., food stamps/SNAP, Medicaid)."

You have a problem with this, send Boehner a letter and tell him. He and McConnell refuse to put comprehensive Immigration Reform in a bill solely for political reasons. Their base wants 'em all deported, as you likely do. The fact is to do so is fiscally irresponsible as each person is required do process, including representation by an attorney.
There is also a factor of concern to all but the most callous conservatives, the so called anchor babies, a topic which might require a repeal of a part of the 14th Amendment (read section one), and those children brought into the United States as minors who have no experience living anywhere else and in many cases speak and understand English only.
