Julianna Margulies won the Emmy on Sunday for best dramatic actress for her performance in "The Good Wife."

Margulies, 45, plays the conflicted spouse of a disgraced district attorney in the CBS legal series.

It was a second Emmy for Margulies, who won in 1995 for her role as nurse Carol Hathaway in the long-running TV hospital series "ER," and was seen as a clear favorite this time around.

The actress already has a Golden Globe and a Screen Actors Guild trophy for her performance as the sometimes dutiful, sometimes resentful wife who goes back to work as a lawyer while her husband rebuilds his political career.
