I say, and with God's success: It is permissible for a Muslim to marry a Jewish woman even if she remains in her religion, as well as a Christian woman; this is based on the saying of Allah, the Exalted: {Today, all good foods have been made lawful, and the food of those who were given the Scripture is lawful for you, and your food is lawful for them, and [lawful in marriage] are chaste women from among the believers and chaste women from among those who were given the Scripture before you}[Al-Ma'idah:5]. This is provided that he does not fear for his religion or the religion of his children from being influenced by the beliefs of the Jewish or Christian woman. A Muslim may be prohibited from marrying a corrupt Muslim woman if he fears for his religion or the religion of his children from her, and Allah knows best.
