AIPAC has a checkered history, generally taking extreme positions against the rights of Palestinians. AIPAC lobbied for the AUMF vote on Iraq and opposed the nuclear deal with Iran:

Indeed, AIPAC took no official position on the invasion of Iraq, but a lot of people, including two members of Congress, report that they were lobbied by AIPAC and/or its membership to support the war. AIPAC can continue to deny its role in lobbying for the Iraq War, as much of the alleged lobbying occurred behind closed doors with members of Congress and few witnesses. But Obama may have had a more limited audience in mind when he warned that “many of the same people who argued for the war in Iraq are now making the case against the Iran nuclear deal.” Members of Congress who are currently being lobbied by AIPAC to reject the nuclear deal with Iran might look back and remember meetings they had 13 years ago when AIPAC members came to their offices. Obama is betting that congressional approval for the use of force against Iraq came up in those meetings, even if AIPAC chose to wash its hands of responsibility for what came next.

AIPAC Bristles at Obama’s Reminder of Iraq War Lobbying

Bernie chose not to speak to them, but Hillary spoke to them today:

Clinton also came out forcefully against the BDS movement (Boycott, Divestment, and Sanctions), which seeks to exert pressure on Israel to change its policies toward the Palestinians. I’m not going to wade into the debate over BDS, but it was striking that Clinton took what is essentially the position of maximal opposition to BDS: not that it has legitimate arguments to make even if it often takes them too far, or that the movement tolerates anti-Semites within its ranks, or that people within it are starting from liberal values and thus might be persuaded to agree with someone like her, but that the entire thing is anti-Semitic and therefore must simply be fought: “Many of the young people here today are on the front lines of the battle to oppose the alarming boycott, divestment and sanctions movement known as BDS. Particularly at a time when anti-Semitism is on the rise across the world, especially in Europe, we must repudiate all efforts to malign, isolate and undermine Israel and the Jewish people. I’ve been sounding the alarm for a while now. As I wrote last year in a letter to the heads of major American Jewish organizations, we have to be united in fighting back against BDS.” And she took on Trump for saying in February that when it comes to negotiations between the two sides, he would attempt to be “neutral.” His opponents in the Republican primaries have gotten a lot of mileage out of that one word, and Clinton used it against him as well: “Yes, we need steady hands, not a president who says he’s neutral on Monday, pro-Israel on Tuesday, and who knows what on Wednesday, because everything’s negotiable.”

Washington Post, The Plum Line: "Hillary Clinton gets to Donald Trump’s right on Israel"

Constructive criticism for Hillary. Don’t undermine President Obama’s foreign policy with Israel and the middle east. Don’t telegraph to Netanyahu that it is open season on Palestinians if you are elected. Please learn from your vote on the Iraq AUMF that contributed to so much death.

Running as a war hawk will not help you with Democratic turnout.

Update I: Rather than address the content, some Hillary fans attempt to distract by contending that Bernie wanted to speak by satellite and AIPAC demanded attendance. If true, it changes nothing. Hillary again showed why she has not learned from her Iraq vote.

Update II: Deleted the statement that Hillary fans use to distract from substance. Regardless of Bernie, Hillary’s position gives a blank check to Netanyahu.
