He is a bloody anti-Semite.
Weekly Standard recently noted Paul's "lucrative and decades-long promotion of bigotry and conspiracy theories, for which he has yet to account fully, and his continuing espousal of extremist views, that should make him unwelcome at any respectable forum, not only those hosted by Jewish organizations."
As you can see from this video, he is not willing to account for it even now.
These are the rantings of a Jew-hater. Period. The Jewish people have been the target of Islamic jihad since the creation of Islam. The modern state of Israel is in a state of constant readiness beause of the relentless jihad war aginst the tiny Jewish state. Jihad came to America in 1993; that Paul would advance a Jewish blood libel reveals who and what he is.

Here is an eye-opener for the uninitiated.
From Red State -
Yes, you read that correctly, Ron Paul endorsed Cynthia McKinney in 2008. For those who do not know, Cynthia McKinney is a certifiably insane anti-American anti-Semitic lunatic. She first came to widespread public attention when she was arrested for punching out a member of the capitol police who tried to stop her when she wasn’t wearing her pin. Cynthia McKinney is so crazy that she got defeated in a primary by a guy who thought Guam might tip over and capsize. McKinney was once arrested by the Israelis while trying to give aid to Hamas and penned a bizarre anti-American and anti-Israeli screed. See more of her anti-Americanism here.
UPDATE: In the CNN interview, Paul said he didn't write the newsletters, didn't read them, and didn't know what was in them. But here he is promoting his newsletters on C Span in 1995 (hat tip armaros). Watch at about 1:40:
