(JTA) — Moderate Democrats backed by political action committees affiliated with the AIPAC pro-Israel lobby won hotly contested Democratic primaries Tuesday, which the group said was a vindication of its controversial decision to dive into direct campaign funding. In North Carolina, Don Davis won handily in the 1st District, in the state’s northeast, besting Erica Smith. In the 4th District in the state’s center, a state senator, Valerie Foushee, defeated Nida Allam, a Durham County commissioner who was the first Muslim woman elected to office in the state, 47% to 37%, with 84% of the vote counted.
