At the Iowa Ag Summit, dozens of potential presidential candidates had similar answers to questions about varying topics—except for Jeb Bush, who veered from the pack on the topic of immigration reform. The former governor stood by his controversial position that a path to legal residency for undocumented immigrants currently in the U.S. is necessary for any plan to reform the immigration system. "We need to fix this broken immigration system," Bush told the audience. Only South Carolina Sen. Lindsey Graham had a similar stance out of the politicians being surveyed. He said immigration is going to be critical for continuing to grow the American economy and to pay for the aging population's Social Security benefits.
