Early on it looked like a 3 horse race as Katic, Ellen Pompeo, the eventual runner up from "Grey's Anatomy" & Jennifer Carpenter "Dexter were within mere votes of each other for the 1st couple days. However, eventually the rush of support for Castle pushed on & eventually eliminated Carpenter from contention & in the last day had enough of a push to give the modest breathing room Stana had over Ellen to turn it into a comfortable win. This category was influenced stats wise by a rush of voters that came in from The Walking Dead, as their fans voted on the awards that their show ere in at that time in the sci-fi/fantasy categories, which were on at the same time as the Action/drama categories. Michelle Dockery from "Downton Abbey" and Mireille Enos of "The Killing" got left behind early by the throngs of supporters for the top 3. Eventually Katic, the actress who plays "Castle" detective Kate Beckett triumphed.
Stana Katic beat runner up Ellen Pompeo by 281 votes. In 3rd was Jennifer Carpenter 292 votes out of 2nd & 635 votes ahead of 4th place Michelle Dockery who finished 306 votes ahead of the final finalist Mireille Enos.
Stana Katic wins this award for the 2nd year in a row. She is also the only actress to make the finals last year & this year in this category. Despite being in the same roles last year, Pompeo, Carpenter & Dockery were not even nominated last year, and Enos didnt get out of the nomination round... of course, with the "Sci-fi" category now being re-named "Sci-fi or fantasy" category, nominees from Once Upon A Time & Game Of Thrones who provided challenges last year have moved, leaving the door open for new challengers.
