By Shira Li Bartov(JTA) — Sen. Bernie Sanders has urged Democratic leaders to ban super PAC spending in primaries, focusing on the efforts of pro-Israel lobbyists to influence a crucial Michigan Senate race. He said in his letter that Democratic leaders did “not have to wait” for that, urging the party to immediately “prohibit super PACs from participating in its primaries.” “Millions of Democrats are AIPAC members who are proud to help elect principled Democrats,” AIPAC said Monday in its response to Sanders. “This letter isn’t about democracy or campaign finance — that’s why he doesn’t name the billionaire super PACs that back him,” the group said on X. In April, a record number of 40 senators voted for his “Block the Bombs” resolutions to ban certain weapons sales to Israel.
