Despite a turbulent two decades the structure of American corporate lobbying has barely changed | LSE United States Politics and Policy
Firms have consistently accounted for about 45 percent of lobbying and have not become more central in lobbying networks.

For those interested in Dutch politics: Far-right leader, Geert Wilders, just pulled the plug on the government coalition that his party PVV was a part of. Because other parties are not “signing up to his party’s asylum plans” May I add that this happened as his party was slipping in polls…
