They would choose Gingrich, who has already said that he would move the American embassy to Jerusalem and would give White House office space to AIPAC. Sadly, Gingrich's best chance at winning the nomination have come and gone. He is old news. Israel's second choice would be Romney who has been making all the standard answers provided in his AIPAC handout. He is unlikely to move the embassy, but he is likely to throw barrels of money at Israel. This is never out of order. Israel's third choice would be Obama. Obama has already given Israel a lot of support, but he seems to think that he is entitled to something in return. Israel cannot abide such an attitude even for one second. Israel's last choice (among the major contenders) would be Ron Paul. He wants a stop to foreign aid and has made no exception for Israel. If this is what he announces prior to the nomination, we can only wonder at how much worse his anti-srael attitude will be after the election.
