Actually I suspect that a fair amount of his mind was occupied with thinking "Bugger, that was on the low side of the informed pundits' predictions." I'd guessed at a majority of 80, but I'd heard figures from 60 to 100.

Blair's biggest danger is now his own party. What he can't do any more is to push controversial issues through, which used not to be a big problem because the size of his majority meant he could ride through any plausible back-bench rebellion. If he tries something like going to war again (for example), he's going to have to persuade an awful lot of people who know full well that it will lose them their seats, and most of them really won't be keen. I'm hoping that this has spiked the ID cards issue, though it's always possible that he'll find some way to make it attractive to the Tories.
