Michele Bachmann ad slams Rick Perry on immigration
The ad criticizes Perry for supporting giving in-state tuition in Texas to illegal aliens and for opposing the Arizona immigration law. It also points out that "[Perry's] financial backers even killed immigration enforcement in Texas". That's a reference to this:
As two of Texas' most politically-involved business leaders emerged as opponents, a bill banning "sanctuary cities" lost crucial momentum... HillCo Partners' lobby team, led by Neal T. "Buddy" Jones, is working on behalf of Houston home builder Bob Perry and San Antonio grocery store magnate Charles Butt to alter a proposal that would permit law enforcement officers to inquire about the immigration status of people they detain, Jones' partner Bill Miller confirmed.
Bob Perry is a contributor to the (unrelated) Rick Perry.
[Perry] signed a bill back in 2001 allowing children of some undocumented immigrants to qualify for in-state tuition for college; the bill was later dubbed the so-called Texas Dream Act for its similarity to federal proposals to give American-born children of undocumented immigrants a pathway to citizenship.
The bill Perry signed was for those who are themselves illegal aliens, irrespective of their parents status(es). And, the DREAM Act is also for those who are themselves illegal aliens; those who are "American-born" are U.S. citizens under the current interpretation of the 14th Amendment.
