"Politics, just as economic pursuits, may be a man's avocation or his vocation. One may engage in politics, and hence seek to influence the distribution of power within and between political structures, as an 'occasional' politician. We are all 'occasional' politicians when we cast our ballot or consummate a similar expression of intention, such as applauding or protesting in a 'political' meeting, or delivering a 'political' speech, etc. The whole relation of many people to politics is restricted to this."
