The impact of political lobbyists remains highly controversial. No-one has explored when they matter. This book tells readers when lobbyists count and analyses the relationship between lobbying, policy outcomes and the impact of external factors to reveal the professional lobbyist's limited effect on policy. On most policy issues lobbyists simply do not matter. But, on rare occasions lobbyists can make a difference and this book explains when they matter and why. | The Persuaders by S.
