Hillary Clinton and Barack Obama are not that far apart on many of the issues. But when it comes to their spouses, the differences couldn't be more glaring.

The Wall Street Journal reports today about the evolving role of Michelle Obama. The Princeton and Harvard Law-educated wife of the democratic front-runner has become an influential adviser. She's been nicknamed "the closer" because she often pushes harder to seal the deal with voters than Barack does. She generally stays away from discussing policy and strategy, but gets very involved with issues that affect her personally, like being a working mom.

Michelle has also given people a peek into their personal lives: Barack snores and doesn't put the butter back in the refrigerator.

She says part of her role is to "give people yet another slice of who Barack is, making him even more multidimensional." She says her comments about his foibles were so people wouldn't "deify" him.

Then there is the other spouse in the race. That would be the 42nd president of the United States.
