Add Rep. Mark Martin, R-Twilight Zone, with his new "Off the Marble," to the ranks of legislative bloggers. Tip from Twittering Tolbert. (Who, despite his GOP affiliation, is breathlessly tracking Bill Clinton's legislative appearance.) Still more Clintonian Tweets from Rep. Duncan Baird, R-Republandia. And, from Right Field, Martin Tweets about "partisian hacking." Yes, I wrote partisian.
