Olympia Snowe's op-ed as to why she's leaving the Senate evokes more questions than it does answers. Specifically, what is she planning?

For change to occur, our leaders must understand that there is not only strength in compromise, courage in conciliation and honor in consensus-building — but also a political reward for following these tenets. That reward will be real only if the people demonstrate their desire for politicians to come together after the planks in their respective party platforms do not prevail.

I certainly don’t have all the answers, and reversing the corrosive trend of winner-take-all politics will take time. But as I enter a new chapter in my life, I see a critical need to engender public support for the political center, for our democracy to flourish and to find solutions that unite rather than divide us.

I do not believe that, in the near term, the Senate can correct itself from within. It is by nature a political entity and, therefore, there must be a benefit to working across the aisle.

She sounds like she’s plotting a third-party presidential run. This sounds like someone who’s planning something big, not someone receding from public life.
