If you want to understand why, here's Bernie Sanders on "Meet the Press" this past Sunday:
KRISTEN WELKER:Okay, and I want to follow up on what you — you just said. Dr. El-Sayed has made Israel a central issue in his primary. He said he, quote, “often struggles with the question of whether Israel has the right to exist as a Jewish state.” In the past, Senator, you have been quite clear that you do support Israel as a Jewish state. Should Dr. El-Sayed speak with the same clarity?SEN. BERNIE SANDERS:Look, I think right now the immediate issue of the moment is whether or not we continue to put tens of billions of dollars into the extremist Netanyahu government, which has killed 75,000 Palestinians, mostly women and children, wounded 150,000, destroyed their infrastructure. And what the American people are saying overwhelmingly, Democrats, many independents — the majority of independents, and many Republicans, especially younger Republicans, “We’ve got better things to do with our money than to continue to fund the military of Israel.”
So the answer to the question as to whether DSA candidates should "speak with the same clarity" is "no." Never answer the question directly and without equivocation or the antisemitism at the heart of the modern Democrat party might be revealed.
Flashback - "Shapiro says Harris aides asked if he was Israeli agent." Remember that one?
