I've been whining about it for awhile now, and it seems I've finally gotten my wish - the Chron now has a Texas politics blog. It's all R.G. Ratcliffe so far, and I'm not sure how interactive he's going to be (responding to comments, linking to stuff outside the Chron, etc), but he's blogging, and I'm happy to cut him some slack until he gets his sea legs, so to speak. Check it out.
