Jeb Bush has officially announced his candidacy for the Republican nomination for president. John Heilemann and Mark Halperin, co-managing editors of Bloomberg Politics, hosts of Bloomberg TV's "With All Due Respect," and the co-authors of Game Change and Double Down: Game Change 2012 (Penguin Books, 2014), talk about Jeb's announcement, his candidacy and other 2016 campaign news.

.@jheil says by the end of the speech, Jeb Bush was firing on all cylinders -- we hadn't seen that from him yet.
