Latest in the series of "why'd he do it?" is Ryan Lizza's New Republic piece. I'm going to ruin the ending for you:
Every governor or senator thinks about running for president. Most do so because they are ambitious and see the presidency as the next rung on America's political ladder. The big question they often ask is strategic. How can I make it through the process and get elected? In the end, that's not the question Warner asked. His advisers swear that the nuances of the primaries and the details of how to topple Hillary Clinton never came up in his final deliberations. Warner asked not whether he could be president, but whether he should be president. The irony of Warner's answer is that the kind of person who dwells on that question is the kind of person you want to be president.It's hard sometimes for me to think that we're not in big trouble in this country, exactly because I can't solve the Lizza dilemma -- just what sort of person would subject themselves to this process in this day and age who would also be the sort of person we'd want to lead us? Read Lizza's description of the pre-campaign thus far and answer me that.
