Ron Paul, Mitt Romney, and then Fred Thompson.
Though there were several questions that I would have rather not picked an answer for.
Question #4: Kick them all out with prejudice was not an answer.
Question #5: Ditto, plus fine them tens of thousands of dollars each, as well as charge for any welfare received on top of that. Then, begin to consider applications to get back into the country, but actually only let their applications process if there are no other immigrants who haven't entered illegally applying.
Question #6: By realizing it's not the government's responsibility.
Question #7: Ditto
Question #8: Abolish it entirely.
So my results may be skewed considering they didn't have the correct answers for 5/11 of the questions.
