 Bill Clinton's longest speech. Bill Clinton's speech was not very well received, though, at his convention, when he had what was previously the longest speech ever delivered at a political convention. He was booed off the stage by his own crowd, by the Democrats at the Democrat convention, with Bill Clinton going on and on and on. And then he finally said, and in conclusion, and the crowd went wild and cheered, like, finally, shut up. But that was not the case last night.
