Make Bernie Sanders support his position.
There's a host on Air America Radio called Thom Hartmann. I like him, I think deep down he's against open borders, but generally all the hosts on all the shows on Air America avoid this issue (Al Franken would constantly remark "I just don't know enough about the issue") Anyway, Hartmann has Vermont Senator Bernie Sanders on every Friday morning for 1 hour starting at 9:00 Pacific, and he takes a lot of calls from listeners. Call Bernie with thoughtful questions and pin this guy down on the position he intends to take.
The caller comment line, which you can call and on which you can leave a message 24 hours a day, is 503 323-6620. The toll-free number to call into the show (the only reliable way to actually talk with Thom if you're a listener and want to discuss politics) is 866-440-THOM (8466) for the national show, and 503 248-0620 for the local KPOJ show.
