The Fritz articles might be called shotgun journalism. That is, most major (and many minor) complaints about Congress were touched upon. But the wheat was not separated from the chaff. So Sen. Jake Garn (R-Utah) is upset. I would be upset too if I had lost my committee chairmanship. But does that mean that there is a problem? The series provided no clarification. Important problems were often passed over in a sentence or two, while minor gripes were given extensive attention.
There are important internal problems in Congress. Most notable is the amount of time that legislators spend on representative and electoral activities (including raising money) to the detriment of legislative work. Following that is the increased influence of interest groups, inadequate oversight, megabills, increased use of the filibuster and increased House Republican obstructionism. To the extent that these issues were discussed the series was useful.
Not all recent changes in Congress are problems. Some, such as increased obstructive behavior by House Republicans, are. But some (member independence) are definite improvements over the past (the absolute power of chairmans); and others are creatures of necessity (megabills), designed to keep a bad situation (lack of White House vision) from getting worse. The articles would have been vastly improved if some of these distinctions had been made.
