The hawkish Emergency Committee for Israel is targeting two more imperiled House Democrats , Virginia's Glenn Nye and Connecticut's Jim Himes, with ads attacking them for signing a letter pressing Israel to ease conditions for civilians in Gaza and warning it to avoid "collective punishment."

The ad, a version of which already aired against Ohio Rep. Mary Jo Kilroy, notes that most House Democrats wouldn't sign what it calls "anti-Israel letter" and suggests viewers ask the members why they "joined an assault on Israel."

The next to air, targeting Nye, is above.

The ads pit ECI -- chaired by Gary Bauer and Bill Kristol -- against the left-leaning J Street, which circulated the letter, and they attempt to exact a cost for deviating from both congressional parties' traditionally near-total support for Israel's security policies.

"Glenn Nye signed onto a letter accusing Israel of 'de facto collective punishment," said ECI adviser Michael Goldfarb in an email. "This is a de facto accusation of war crimes against one of our closest allies, which is why 88% of the House refused to sign the letter. We plan on making sure that voters know if their representative is signing anti-Israel letters, taking anti-Israel votes, or doing anything else to undermine the US-Israel relationship."

(The letter, in fact, doesn't literally accuse Israel of the act. It says that Israel's security concerns "must be addressed without resulting in the de facto collective punishment of the Palestinian residents of the Gaza Strip.")...
