I believe she was Jewish before and after WWII as well.
The single thing that hurt Allen the most was the "macaca" comment, and the Washington Post went all out using that story against him. In the end the election was extremely close, and any one of several factors could be considered decisive (like the overwhelming Muslim vote for the Democrat). The loss of that seat gave the Senate to the Democrats, but George Allen's inability to handle the "macaca" nonsense showed that he wouldn't have been the candidate the Republican Party needed for President in 2008.
More than Allen’s “inability” to address the macaca incident - he legitimized it.
He screwed-up BIG time, in a way I have seen few times over the course of my life. He absolutely legitimized a horrific attack against him, and never recovered.
He went from top Presidential contender to career over because of his bullheaded refusal to take on the issue, and instead hope he could, essentially, apologize for being a racist and hope that would be the end of it.
I always loved George Allen, but he proved that he was not ready for a promotion of any kind. He was never really ready for a challenged race of any kind.
