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.
They demonstrated their significance after David Davis resigned. The mainstream media assumed that Davis had gone mad and that this was a disaster for Cameron. But the Conservative blogosphere was exultant at this principled gesture in defiance of orthodox politics.
If their party wins power then mainstream Conservative blogs have a dilemma. Blogger Iain Dale is not a slavish Cameronite. He has spoken out against mainstream Tory opinion on occasion. But he wants to be a Tory MP and agrees with most of what his leader thinks. He is a lovely writer and a quick-footed online entrepreneur who has done much to popularise the genre. He now runs a neutral political wonk magazine called Total Politics, which seems to suggest he doesn't see much of a future for online political comment from a Tory perspective.
Likewise, Tim Montgomerie has had the backing to create Britain's most sophisticated political activist blog, ConservativeHome. It has taken the party to task on some issues and has a good feel for grass-roots Tory thinking. Will it be able to maintain even a moderately critical stance without upsetting the new occupants of No 10? In other words, are the Tory bloggers there for a debate or for power?
Guido Fawkes (Paul Staines) has been a terrific attack dog against what he sees as the corruption of New Labour. He spurred on mainstream media to help bring John Prescott down. But what does Staines do when David Cameron crosses the No 10 threshold? He professes to be a libertarian but he is definitely a rightwing one. However, he is not a Conservative with a capital C. He feeds off the Westminster journalists and advisors for his insider information. Unless Paul goes into rosé-drenched retirement in Provence, I reckon he will be tempted to take on the Tories as well.
Tory bloggers may well become her majesty's official online opposition. Meanwhile, the future of the Labour party will depend on its ability to come up with new ideas and an active supporter base. It's time for the leftwing blogs to grow up and prepare for power.
So what do you make of that? I reckon there are enough holes in his argument to create a sieve. The problem is, that if Labour go into opposition they will be like rats in a sack. LabourHome has completely failed to emulate its Conservative equivalent, partly, it has to be said, because it doesn't have anyone running it full time, like ConservativeHome does. Liberal Conspiracy is an interesting new site and has the potential to become a big player, but it seems to me from my less than frequent visits that it is more interested in attack dog politics than anything else.
One thing we all learn as bloggers is that you cannot please all of the people all of the time. There was a ridiculous post about me on a blog I had never heard of before called Welsh Ramblings (a blog which certainly lives up to its name). The author (who styles himself Lenin Cymru) described me as a Tory mouthpiece. I pointed out that I doubted whether Boris Johnson or Ken Clarke would agree with that description. He then wrote...
Well, you have to have criticise the Tories sometimes to increase your credibility as an 'impartial' blogger.
I can't win, can I? If I say something positive about the Tories I am a mouthpiece, and if I criticise them just do it to appear impartical in a tokenistic kind of way. So I think I will continue to do what has brought 70,000 readers a month to this blog - call it as I see it. And that will continue whether the Tories are in opposition or government. Got that, Charlie?!
