Blair is right wing I'll agree, however people have ideas, and other people get them done. Mr Blair isn't one to get things done as the current state of things like the NHS show.. (Lets not go down the Thatcher route of argument again
although Camerons in the same party, he's not the same person
)
And anyway.. Blair won't be up for re-election next time, it will be the ever-so-slightly-more-left Brown i'd imagine
