The final is decided by the fact that X-Factor finishes a week earlier, so you have loads of teeny girls voting on Strictly for the first time.
They have no idea who has danced what in the past weeks, and only go by what they have read in celeb magazines or tabloids etc.
They may not even know who 2 or 3 out of the 4 finalists actually are
Natalie had previously played a "nasty character" in Corrie, so the new voters only saw that. Abbey was a glamourous model with a WAG lifestyle they all want to emulate, so that explains her vote.
Last year Caroline Flack won, as the tweenies knew her from the previous year's X-factor.
Look at the recent winners of Strictly, they all appeal to young teenage girls.
Either young male hunks like Harry Judd or Louis Smith, or "sweet" girlies like Flack, Clancy or Tointon.
My opinion is that to be fairer to the regular Strictly viewers and voters is that they should also add the votes from previous weeks of Strictly that each celeb got, so that the final is not decided by teeny girls only voting on Strictly as X-factor has ended.
This way, great dancers like Natalie Gumede, Sophie Ellis Bextor, Simon Webb etc would get a fairer crack in the final.
They would not lose out just because 14 year olds have never heard of them, or cannot seperate the person from the character they played in a soap
