Given that Tony has taken Labour so far right that there was really no room for any kind of sane politics to his right - without getting into the kind iof crazy stuff they have across the Atlantic, which just wouldn't have a chance here (thank God and touch wood) - it makes sense for the Tories under Spliffy Cameron to move back to the moderate right-of-centre position that Blair has colonised.
So instead of "vote for us because we believe in different things" it becomes "vote for us, because we can do the same things better, and it's time for a few new faces".
What's the betting they'll change the name, as a kind of symbolic equivalent to the way Tony dished Clause Four? "Vote One Nation".
