The Montana GOP E-brief says that Brian Schweitzer's blog has been dropped from his website. I checked the site and found the blog, but it hasn't been updated since May 20 - which makes his posting record worse even than mine. Also, the blog doesn't appear to be linked to the home page.
The GOP's dubious interpretation is that Schweitzer couldn't take the heat in his comments section. My guess is that Schweitzer, like this editor, has trouble finding the time to keep up with it.
