If you are running for office you have to be prepared to answer questions. Tough questions, sometimes. You have to be prepared to take criticism. Just think. If you are elected you will have David and Penny Elsebush railing at you every meeting, you will have Tad calling you a Nazi at every meeting. And that's just for starters. And you have to listen respectfully, and you sometimes have to engage in discussion, whether you want to or not.
Campaigning helps you develop a thick skin, and prepares you for what is to come.
So, If you are going to use the blog as if it were a website, which is entirely respectable, then don't allow comments. Use it to post your positions, and articles and supporters' names, and links to things you consider to be important, just as you would on a website. Nothing wrong with that. It is a web presence, and that is what matters. Blogger even advertises its blog site as a website.
But - if you are going to have a campaign blog, one which allows comments, and pretends to be open for discussion, then allow the comments. Maybe even consider responding to the points and questions. Because if you get elected, you're going to be representing all the people.
Are you getting 'blocked' on George's blog? I'm hearing from people who are. Maybe the "George Clark Blog Team" is off on vacation or something.... or maybe George is into censorship, or maybe he doesn't want to answer any questions. People are asking. See if your comments/questions get through - georgeclark08.wordpress.com/
