There's a list of tough questions from Phyllis Schlafly here, which, as with this site, she's encouraging others to ask at town hall meetings. The immigration-related questions are summarized here. Samples:
...Do you consider it a presidential duty to prevent illegal entry into our country?
...Will you pardon the two Border Patrol agents who stopped an illegal alien from bringing in a million dollars worth of illegal drugs, and now face 11- and 12-year sentences while the drug smuggler was given immunity from prosecution?
...Will you veto any plan to put illegal aliens on a path to citizenship without going home and getting in line for lawful immigration?
The last is a bit problematic due to the new scam: a "touchback" provision in the Flake-Gutierrez amnesty that would require current illegal aliens to symbolically return home, at which time they could apply for re-entry as legal permanent residents.
