2. A lot of former Congressmen do work similar to lobbying but don't register.

3. Committee and Party leaders.

4. Former members generally specialize in access that they then sell to multiple clients.

5. Lobbying organizations get more power to influence policy-making.

6. For every $1 spent by public interest groups, $34 is spent by corporations.
