I think if the contest remains a basis of reward for 'talent', then Alexandra will walk it - but as well know, the public do not always think like that.
I am sure Alexandra will go onwards and upwards because she has the package - the looks, the moves, and of course, the pure vocal talent.
I am amazed how wooden and dumpy Britney (38m albums worldwide) Spears looked beside her - and her 'people' mumbled something about her being unable to perform a dance routine and sing at the same time. OK, that's fair enough - but don;t show youeself up on a stage with a group of amateurs who can, and do just that every week.
Leon's career seems to be rather like Leon - around, but totally colourless and uninteresting.
