Maybe this is why Barack Obama is so upset with Sen. Joe Lieberman and his support for John McCain. He may be sensing important Jewish support slipping away:

Sen. John McCain (R-Ariz.) is attracting elite Jewish Democratic donors who backed Sen. Hillary Rodham Clinton (N.Y.) and are concerned about Sen. Barack Obama’s (D-Ill.) stance toward Israel, say McCain backers who are organizing the effort to court Democrats.

McCain has already had several fundraising events with Jewish Democrats in Washington and Florida, say his supporters.

He also has the backing of Democrat-turned-Independent Sen. Joe Lieberman (Conn.), who made history as the first Jewish vice presidential candidate and has recently raised questions about Obama’s foreign policy vision for the Middle East.

Stephen Muss, the Florida developer, is the biggest Democratic donor and fundraiser to pledge his support for McCain and the Republican National Committee, said a GOP official. Muss has given tens of thousands of dollars to help Democratic candidates in recent years, including $80,000 to the Democratic National Committee (DNC) in 2000, according to the Center for Responsive Politics and CQ MoneyLine.  read more »
