Mitt’s problem is credibility. He claimed in the last debate that he would deport all 12 million illegal immigrants, which is impossible. There aren’t 12 million jail cells available to process these people.
More realistic and honest: Deport the 2 million illegals who have a criminal record. That would be doable.
Mitts always argued that by securing the border, enforcing the laws and removing the magnets that attract the illegals (free benefits, illegally obtained jobs, health care, sanctuary cities etc), they will remove themselves through attrition.
The key is that he supports securing the border once and for all and he rejects the Z visa which would give the illegals immediate and indefinite legal status.
Plus, Tom Tancredo thinks Romney's plan is acceptable. That's good enough for me and preferable to what McCain, Huck or the dems have in store.
It is easy to deport 12 million. You dry up the benefits like a place to work and handouts. They are not that dumb. They will hear the sounds of home calling after that.
