More immigration questions for Barack Obama (change.gov Open for Questions)

Barack Obama's change dot gov is starting round two of their "Open for Questions" scam (why it's a scam is explained here) where they solicit questions from the public at change.gov/openforquestions. In addition to re-submitting a question I asked in the first round, I just submitted four more. As before, I was greatly hampered by the 250 character limit, causing much editing. However, these are tougher than anything else I've seen there and will assuredly be much tougher than the "winning" questions (source links added) (1/13/09 UPDATE: Final vote totals added in up/down votes format):

1. You spoke at an immigration march that was organized by people linked to the Mexican government. Shouldn't senators investigate a foreign government pushing their agenda inside the U.S., and not help that government push their agenda as you did? (source) (21/10)

2. In May, you said "hate crimes against Hispanic people doubled last year". Even your friends at FactCheck admit that's a lie, and when asked you were unable to document your claim. Would you care to issue a retraction? (source) (3/12)

3. Won't millions of foreigners see the immigration "reform" you support as an amnesty, whatever euphemism you want to use? And, won't many respond by trying to come here? And, won't some of them die in the desert due to your "humanitarian" "reform"? (13/11)

4. You're repeatedly offered a "false choice" between either mass deportations or immigration "reform". What about attrition, a proven plan that would reduce current & future illegal immigration and which would lead to reform in the sending countries? (source) (67/42)

UPDATE: For completeness' sake, here's the other question (linked above):

You support giving in-state tuition to illegal aliens. But, each such discount given to an illegal alien represents one that's taken away from a U.S. citizen. What would you say to a U.S. citizen who can't go to college because of what you support? (99/97)
