It was a good speech, but the LDS Baptism of holocaust victims and other dead Jews won't help him any in the primary or the general with the Jewish vote, a constituency that can tip elections in FL and NY. In fact, it could hurt him enough to tip some states, and that's not even taking into account the problems evangelicals have with mormonism. It will be a factor.
But, he can certainly talk a good game. So could Clinton, unfortumately and it will take more than words.
We will see what unfolds.
