The conventional wisdom is that Joe Biden has been staying on the sidelines, waiting to see how bad the email scandal gets for Hillary. But while that might be true, consider that Biden need not just be a passive player in the game. There is a plausible theory by which Biden's entry into the race by its very fact would increase the odds of Hillary encountering legal travails.
One reason that President Obama might be holding off on having his DoJ go after Hillary is that he doesn't want to destroy the candidacy of the only plausible Dem candidate in the race. As brilliant and charismatic as is Lincoln Chaffee, still he might just not do.
