His competition for the award is: John Slattery (Mad Men), Alan Cumming (The Good Wife), Andre Braugher (Men of a Certain Age), Walton Goggins (Justified) and Peter Dinklage (Game of Thrones).
And looking over the category, strong as it is, I think Charles has an excellent chance of winning the award. While he has had a career that includes strong performances in quality series like "In Treatment" (HBO) and "Sports Night" (ABC), this would be his first Emmy.
"I guess I would just say that I am really humbled and honored to have my work recognized," Charles said Thursday in an email to the Sun.
"I just got back from being out of the country so I am a little bit jet-lagged, but have been really touched by the calls, texts and emails from family and friends," he added. Charles had been in Israel.
This is his first nomination for "The Good Wife," despite his strong performance as an attorney who has a history and a spark for a fellow lawyer played by Julianna Margulies. She was again nominated Thursday for best actress in a drama.
"The Good Wife" was nominated as outstanding drama in a category that includes "Boardwalk Empire," "Mad Men," "Game of Thrones" and "Friday Night Lights." Best drama is considered the most prestigious Emmy.
Baltimore native Julie Bowen was also nominated Thursday for her portrayal of Claire Dunphy on "Modern Family" (ABC). It was Bowen's second nomination in the category of best supporting actress in a comedy for her work on the show.
