Emmys 2011: Who Deserves the Award for Supporting Actress in a Drama? Vote Now!

A pair of Emmy newcomers will face off against three prior winners and returning nominee in the 2011 race for Best Supporting Actress in a Drama Series. Versatile character actresses Michelle Forbes (The Killing) and Margo Martindale (Justified) enter the primetime Emmy fray for the very first time, while Mad Men‘s Christina Hendricks (nominated for the second straight year) aims to get her first win by the end of the 2011 ceremony. Those women will be up against a trio of actresses looking to score bookends to their initial Emmys: Last year’s champ Archie Panjabi (The Good Wife), as well as her costar Christine Baranski (a winner in 1995 for Cybill) and Boardwalk Empire‘s Kelly Macdonald (honored in 2006 for The Girl in the Café).
