President Obama won re-election by mobilizing the coalition of the ascendant...people of color and young voters. Everyone knows that the Republicans are toast unless/until they find a way to connect with the changing face of America.
I don't know yet if Hillary Clinton plans to run in 2016 - at this point I'd give it slightly better than even odds. But if she does, the one thing I'll be watching is whether or not she is able to match President Obama's appeal to that winning coalition.
The truth is that due to some of the tension that arose during the 2008 primary, the Clintons have some bridges to rebuild with the rank and file in the African American community (a major player in that coalition). My word of advice to her right now would be that this is a good time to start doing that.
I know that many in the black intelligentsia (ie, the Wests and Smiley's of the world) feel perfectly comfortable in criticizing the President. But based on what I'm hearing, the folks on the ground are having none of that. And so when Bill Clinton suggests that President Obama is a "wuss" if he doesn't intervene in Syria - he might be speaking his mind but he's doing his wife's potential political aspirations no favors. Running against Obama and the coalition he built is definitely not going to work - for the Clintons or anyone else.
Hillary Clinton already has the white baby boomer women's vote all locked up. If she wants to go for it, she needs to get out beyond that demographic NOW - before the spotlight of a campaign begins to shine - and start mending some fences. And she probably needs her husband to STFU when it comes to critiquing President Obama's policies.
Clinton isn't going to win with a majority of white votes any more than the Republicans are. So far I haven't seen that she or her political supporters have recognized that. If she wants to run - she's got some work to do.
