rebdoniel,
The word rabbi means teacher and carries with it an implication that the person is suitable for leadership. I realize that Levin got semichah from somewhere, but anyone who would try to get Jews to vote for a vile anti-Semite like Buchanan is no rabbi — definitely no leader! No matter how much Shas he may have learned, unless he had done tshuvah for trying to mislead the Jewish community he is not be be followed.
