As Tom O'Neill points out, the most obvious omission is Terry O'Quinn from "Lost," who won a couple of years ago and either forgot to submit himself again or decided he didn't care.
After the jump, my own picks, plus the toughest names I had to leave out of each category. Feel free to offer up your own, or simply heckle my choices.
Lead actor in a comedy
Alec Baldwin, "30 Rock"
Steve Carell, "The Office"
Zachary Levi, "Chuck"
Ken Marino, "Party Down"
Jim Parsons, "The Big Bang Theory"
Adam Scott, "Party Down"
Tough omissions: Bret & Jemaine from "Flight of the Conchords," maybe Zach Braff
Lead actor in a drama
Gabriel Byrne, "In Treatment"
Kyle Chandler, "Friday Night Lights"
Michael Chiklis, "The Shield"
Bryan Cranston, "Breaking Bad"
Jon Hamm, "Mad Men"
Edward James Olmos, "Battlestar Galactica"
Tough omissions: Hugh Laurie, Michael C. Hall, Damian Lewis, Jeffrey Donovan
Lead actress in a comedy
Toni Collette, "United States of Tara"
Tina Fey, "30 Rock"
Anna Friel, "Pushing Daisies"
Yvonne Strahovski, "Chuck"
Tough omissions: None. I couldn't come up with four from shows I watch where I like the performance enough. Amy Poehler was very good in a few eps of Parks and Recreation, but too broad in others, as they tried to find that character.
Lead actress in a drama
January Jones, "Mad Men"
Mary McDonnell, "Battlestar Galactica"
Elisabeth Moss, "Mad Men"
Jill Scott, "No. 1 Ladies' Detective Agency"
Jeanne Tripplehorn, "Big Love"
Tough omissions: I would say Holly Hunter, except I stopped watching Saving Grace even though I like her performance. So I only have five, I think.
Supporting actor in a comedy
Donald Faison, "Scrubs"
Neil Patrick Harris, "How I Met Your Mother"
Chi McBride, "Pushing Daisies"
Tracy Morgan, "30 Rock"
Ray Wise, "Reaper"

Tough omissions: Scott Krinsky and Vik Sahay (if only I could nominate Jeffster! as a single entity), John C. McGinley, Brian Baumgartner (for the spilled chili scene alone), Martin Starr, John Krasinski (for the "send in the subs" scene alone), Ed Helms, Jim Gaffigan
Supporting actor in a drama
Justin Chambers, "Grey's Anatomy"
Jeremy Davies, "Lost"
Walton Goggins, "The Shield"
