Is Bill Back?

Donald Trump just gave Bill Clinton an excuse to get back into the game. It's going to be glorious.:

...Now Bill Clinton gets to re-enter his wheelhouse. The most enduringly popular man in American politics now has an excuse to take down Donald Trump because, hey, the other guy started it by hitting below the belt. It means Hillary can stay above the fray and focus on legitimate issues, while Bill and Donald duke it out over the sideshow stuff. It’s the populist opportunity that Bill Clinton has been arguably waiting for since he left office. And it’s going to be a sight to see.
