Things are getting a little tight in Iowa, so it may not be the right time for Sen. Hillary Rodham Clinton to roll out her presidential cabinet.

But should she ultimately get the nomination and then win the presidency, odds are that she might ask the New York City power couple of Joel I. Klein and Nicole K. Seligman to join her team.

And she could also keep things all in the family and sign on Stephanie Seligman, Nicole’s sister, to work at the White House or just about anywhere else.
