95% of the U.S. population in 1790 lived in places of less than 2,500 people.  Presidential candidates did not campaign and win only in big cities. 

The presidential election system, using the 48 state winner-take-all method or district winner method of awarding electoral votes used by 2 states, that we have today was not designed, anticipated, or favored by the Founders.  It is the product of decades of change precipitated by the emergence of political parties and enactment by states of winner-take-all or district winner laws, not mentioned, much less endorsed, in the Constitution.
	
In 1789, in the nation's first election, a majority of the states appointed their presidential electors by appointment by the legislature or by the governor and his cabinet, the people had no vote for President in most states, and in them, only men who owned a substantial amount of property could vote, and only three states used the state-by-state winner-take-all method to award electoral votes.
