Hillary Clinton's former policy director, Neera Tanden, will start next week in Chicago as Barack Obama's Director of Domestic Policy, reporting to policy director Heather Higginbottom, a source familiar with the plans said.

Tanden is the most senior Clinton loyalist to join Obama, a close, longtime aide whose move is not seen in Hillaryland as a defection -- as some saw the early decision of departed campaign manager Patti Solis Doyle -- but as a natural element of the shift to the general election.

She was a key architect of, among other things, Clinton's healthcare plan, whose more aggressive push for universal coverage through mandates became was probably the key domestic policy difference between the Democrats.
