Now Craig, who over the weekend announced that he will step down later this month, is a man with very few friends.
One of his few outspoken defenders in recent days has been a gay, pro-Israel Jewish Democrat from Massachusetts, Rep. Barney Frank. While acknowledging that Craig's conduct was "hypocritical," given the Idahoan's anti-gay rights record, Frank said his crime was "not an abuse of office" and does not warrant resignation.
Frank seemed to be speaking from his experience as an openly gay man, not from his experience as a Jew. But the American Jewish community as a whole should be upset over the Republican rush to drive Craig from office, and not just because as a senator he ended up being a pleasant surprise for pro-Israel activists.
As the late Yale historian John Boswell showed, where there is homophobia, anti-Semitism very often lurks around the corner.
"The same laws which oppressed Jews oppressed gay people; the same groups bent on eliminating Jews tried to wipe out homosexuality," Boswell wrote.
While his study was based on medieval Europe, his words ring true in modern America. Jews may disagree about the status of homosexuals within our own religious communities, but when there is an upsurge of homophobia in society at large, all Jews should take note.
Craig, even though he insists he is not gay, appears to be a victim of homophobia.
Republicans in the Senate and the House of Representatives have long tolerated members in their midst who carried on extramarital affairs - with women. Craig's crime in the court of law is that he allegedly sought to have sex in an airport bathroom, but his sentence in the court of public opinion is so severe because he allegedly sought to have sex with a man.
A double standard is being invoked here, and Jews, as the historical victims of double standards, have a duty to speak up.
The National Jewish Democratic Council is fulfilling that duty, at least in part. In an Aug. 30 statement, the council noted the discrepancy between the GOP's lenient treatment of Republican Sen. David Vitter, the first-term Louisianan whose name appeared in a female prostitute's Rolodex, and its swift punishment of Craig, who lost his major committee assignments after the sex scandal surfaced and was pressured into announcing his resignation.
Yet it is one thing to assail the Republican leadership and quite another to put in a good word for Craig himself. We may condemn Craig's apparent attempt at adultery; we may disagree with Craig's views on almost every topic; we may support the idea of a Democrat winning his Senate seat in 2008. But the fact remains that in the first year after his election to the Senate, Craig underwent a remarkable evolution from isolationist to Israel supporter. While his colleagues condemn Craig's "conduct unbecoming a senator," American Jews should remember Craig's conduct on becoming a senator.
By 1990, Idaho's senior senator, the Republican James McClure, had amassed, in the words of the Jerusalem Post, "one of the most anti-Israel records." Craig, who voted in the House against aid to Israel, seemed likely to follow in the retiring McClure's footsteps.
As a freshman senator, however, Craig reconsidered his views. He visited Israel and spoke out on the Senate floor in favor of a $10 billion package of loan guarantees to pay for the absorption of Soviet and Ethiopian immigrants. Though he is unlikely to appear on any list of the "most pro-Israel senators," Craig has consistently cautioned his colleagues about the threats posed to Israel's security by global jihadists and a nuclear-armed Iran.
The Book of Proverbs instructs us: "Do not forsake your friend." Craig has been forsaken by his own party, but as Craig has shown concern for the fate of the Jews, we should likewise show concern for him.
Of course, Craig's pro-Israel stance is not the only reason why American Jews ought to oppose Craig's ouster. We ought to oppose his ouster because it would signal a victory for forces of hate within the Republican Party.
Seventeen years ago, American Jews tried to prevent Craig from becoming a senator, but now we should be outraged over how he lost his job.
