From your link:
"Truthdig reader Richard Pilkington pointed out by email that there were no formal votes cast for or against Resolution 498. The resolution was passed by “unanimous consent,” meaning apparently that no senator objected. Progressive senators Al Franken and Sherrod Brown co-sponsored the resolution. Senators Bernie Sanders and Elizabeth Warren did not. The language of this article was changed to reflect this clarification."
Sanders was one of the 20 Senators who DIDN'T sponsor/co-sponsor the resolution. 80 did.
Sanders also condemned Israel's disproportion use of force:
"Sanders believes the Israeli attacks that killed hundreds of innocent people – including many women and children – in bombings of civilian neighborhoods and UN controlled schools, hospitals, and refugee camps were disproportionate, and the widespread killing of civilians is completely unacceptable. Israel's actions took an enormous human toll, and appeared to strengthen support for Hamas and may well be sowing the seeds for even more hatred, war and destruction in future years."
Know any other Senators who said anything even near that, or that they were "not a great fan" of Netanyahu?
Sanders has been more critical of Israel than any sitting U.S. Senator and presenting his position as support for AIPAC based on not objecting to a bill is simply wrong.
Do you view yourself as a Zionist?
A Zionist? What does that mean? Want to define what the word is? Do I think Israel has the right to exist, yeah, I do. Do I believe that the United States should be playing an even-handed role in terms of its dealings with the Palestinian community in Israel? Absolutely I do.
Again, I think that you have volatile regions in the world, the Middle East is one of them, and the United States has got to work with other countries around the world to fight for Israel's security and existence at the same time as we fight for a Palestinian state where the people in that country can enjoy a decent standard of living, which is certainly not the case right now. My long-term hope is that instead of pouring so much military aid into Israel, into Egypt, we can provide more economic aid to help improve the standard of living of the people in that area."
