A lobbyist is an individual who tries to influence legislation on behalf of an interest in particular, to assure that laws favor industry and public relations. Lobbyists understand the legislative process in all its nature, that is why they help politicians to make decisions related to laws. They represented all points of view on issues involving the country and through them the citizens' voice can be heard.
On the other hand, democracy is known as the act of exercising the power of the citizens by voting, but it is not a secret that this democratic government sometimes is not what it seems to be. In a constitutional democracy, the power of the citizens can be exercised within the framework of a representative entity.
Lobbyists have the power to influence on a whole government and they have a duty to act on behalf of others. A lobbyist that influence on a governor's decisions should reside their priorities on behalf society and will make a legislator successful by following and respecting democracy system.
To sum up, the quality a lobbyist needs to have to be successful is doing his job on behalf society to respect democracy characteristics.
