Richard Baehr, a very sharp analyst, makes the case for that view here. Baehr:
For the next twelve months, the president will be constrained by the need to win Jewish votes and collect Jewish campaign cash. But if he wins again, in a second term, Obama can be Obama, rather than the panderer in chief of his re-election effort. The president who argued for more distance between the U.S. and Israel in a meeting with top officials of Jewish organizations will really get to create some space.
If we're lucky that will turn into an academic question.
