Today is the final full day of campaigning before Tuesday’s primary election in Maryland. In one closely watched race, former Congressmember Donna Edwards is seeking to win back her old seat in Maryland’s 4th Congressional District, outside of Washington, D.C. She is facing the corporate attorney Glenn Ivey, who has raised seven times as much money. The New York Times reports a new super PAC run by AIPAC, the American Israel Public Affairs Committee, has spent nearly $6 million on the primary race in an attempt to defeat Edwards. Another group with ties to AIPAC, Democratic Majority for Israel, has spent over $425,000 to back Edwards’s opponent. The two groups also poured money into efforts to defeat other progressive Democrats, including Nina Turner in Ohio and Jessica Cisneros in Texas.
