Which WWE Diva has the best chance at beating Trish's record of holding the Womens Title 7 times & why?

I would have to say that the WWE Diva that has the best chance at beating Trish's record of holding the Womens Title 7 times is Mickie James because as you've already stated she's held the title 4 times already, she's one of the better divas on the Raw roster and she should enjoy a nice long career with the WWE.
