In the two days since Jeb Bush’s interesting and provocative interview with Fox News reporter Shannon Bream, many commentators and analysts have parsed his words and offered thoughts on what they mean for a prospective 2016 presidential bid. There’s a good reason for this interest. Bush is a well-regarded former governor of a big state and a favorite of big GOP donors.

Many political reporters, who spend lots of their time talking to those GOP donors, assume that Bush would be the instant frontrunner were he to decide to run. That’s premature, but it’s clear that Bush’s decision will shape the contours of the Republican primary. It’s also clear that the casual musing he has done about a presidential run is much more serious this time. Bush has not only accepted requests to do RNC events this cycle, he’s volunteered to do others. But his comments over the weekend may give us the best window into just how seriously he is looking at a run.
