Jewish Democrats lauded President Barack Obama's victory in the U.S. elections on Tuesday, praising the support given to him by American Jewish voters.

"The powerful support given to the President today by American Jews shows that the more than $15 million campaign undertaken by Republicans to woo Jewish voters with negative advertising, scare tactics, and outright lies simply did not work," National Jewish Democratic Council President and CEO David A. Harris said.

"Since the New Deal, the Democratic Party has been the political home for the overwhelming majority of Jewish voters - and tonight's data affirms that the relationship between the Jewish community and the Democratic Party is as strong as ever," he added.

Steve Rabinowitz, a former press aide in Bill Clinton's White House, who ran a Jewish media hub in support of Obama's re-election, said: "We were out spent by Jewish Republicans by over $40 million dollars and they only have four points and another four years in exile to show for it. Some mazel [luck]."

Alan Solow, former Chairman of the Conference of Presidents of Major American Jewish Organizations and an early Obama supporter, was among the thousands awaiting President's speech at McCormick place tonight: "I have always felt the President would prevail because he was the superior candidate," he told Haaretz. "He took office at a challenging time and has turned our country around. We believe that the race was essentially stable for a long period and that the President would win a relatively close election."

J Street President Jeremy Ben Ami tweeted: "After all the millions, all the fuss, Jewish vote didn't move from Obama. Can myth of the Israel-centered Jewish voter be put to rest?"

Meanwhile, two Jewish Democrats secured congressional seats in Florida in the elections on Tuesday.

Lois Frankel, 64, a former of the Florida House of Representatives and ex-mayor of West Palm Beach, defeated Adam Hasner, a former majority leader in the Florida state Senate, who also is Jewish.

Alan Grayson, 54, the fiery liberal who had been unseated in the Republican electoral surge in 2010, returned to the House by defeating Todd Long in a newly created Orlando-area district.

Jewish democrats at re-elected President Barack Obama's headquarters in Chicago celebrated the victory, lauding the support given to him by the American Jewish community.
