First of all, the problem is that too many in the Democratic base are anti-Semitic, or at least anti-Israel. Yes, I do see those things as sometimes separate, unlike some other Jews.
The other problem
Therefore, according to Politico:
A vote on a resolution condemning anti-Semitism in response to controversial comments by Rep. Ilhan Omar is set to slip past Wednesday amid intensifying pressure from the left both inside and outside the House Democratic Caucus.
An array of progressive groups declared their support for Omar, while both the Congressional Black Caucus and Congressional Progressive Caucus — two of the most important factions among House Democrats — wanted more time to review the situation, lawmakers and aides said.
Speaker Nancy Pelosi (D-Calif.) and House Majority Leader Steny Hoyer (D-Md.) said in a closed-door meeting Tuesday that the vote would likely happen Thursday. They also said a draft resolution would be updated to include additional language rejecting anti-Muslim bias, although some Democratic sources believe that an entirely new document might be crafted.
“We’re still discussing it,” Hoyer said on Tuesday. “The sentiment is that it ought to be broad-based. What we’re against is hate, prejudice, bigotry, white supremacy, Islamophobia, and anti-Semitism.”
So they’ll pass a resolution condemning hatred of all kinds!
Next week, a resolution opposing being mean to people.
