Who is the Worst Singer to Win American Idol? [POLL]

It was just announced the other day that American Idol will shut it down next year after what will be it's 15th season. Idol has had quite a run and has been a great show for years. I loved it when it started and it has had it's highs and lows but I feel the current crop of judges may be the best yet. Everything has a shelf life and I think Idol is leaving at the right time. The talent search shows on TV are starting to run their course and I would be surprised if the rest of them stick around much longer either.

American Idol has crowned a few great champions and some not so great. There are really very few winners who have made any kind of impact on the music world. I would say Kelly Clarkson, Carrie Underwood, Jordin Sparks, Phillip Phillips and Scotty McCreery would go on the successful list and the rest haven't really found the success they expected. There have been other contestants like Jennifer Hudson, Adam Lambert and Chris Daughtry who have made memorable music but were not winners on the show.

Who has been the worst singer to win the title of American Idol? There have been some very forgettable winners but who is at the bottom of the pole? Vote here and let me know who think is the biggest stinker.
