Generally speaking, Beckett gets it right—he highlights the dilemma that Conservative Party bloggers are going to have but, more importantly, hints at one of the main points about the right.
Of course, rightwing bloggers have a very different problem. It's generally accepted that they are more entertaining and more effective. This could simply be because they are in opposition. Perhaps the individualism of blogging better suits the less collectivist mentalities on the right.
This is, of course, correct; the right wing tend to be less collectivist than the left; that is why they are right wing. And the UK blogosphere is dominated (at least in the number of voices, if not the traffic volume) by libertarians who are, by definition, the least collectivist of al.
But this is a subject that been addressed a number of times, most succinctly by Tim Worstall, writing at the ASI blog.
Where I think his ultimate conclusion, that blogs won't be controlled is correct, is with respect to those that lie outside such party limits. For example, Samizdata make no bones about their virulent dislike of Tories, of social authoritarians just as much as economic ones. I've been known to make the same point myself. It's most unlikely that this blog will roll over to have its belly rubbed just because the blue rosettes got into Number 10 either.
For I think there's a fault line that runs through "political blogging" which isn't in fact properly appreciated. There are those who blog for a specific group, for a party, for their tribe. And there are those who blog in support of certain ideas, or ideals. The former group will indeed be liable to capture by the centre ("don't rock the boat old boy, not now we've got back into power again") and the latter will continue to scream for their cherished goals whichever party is in power.
This is, of course, entirely true. Since your humble Devil is a libertarian or classical liberal or whatever you want to call it (and his preferred party is unlikely to be in power any time soon) and not one of the three main parties are of this bent, it is unlikely that the Tories will get any less stick from me than NuLabour do.
Unless, of course, the Tories turn out to be libertarian. At which point you will hear nothing on this blog but the relayed the sound of hair-dryers as I desperately attempt to stop Hell from freezing over...
