With the current system of electing the President, none of the states requires that a presidential candidate receive anything more than the most popular votes in order to receive all of the state's or district’s electoral votes. 

Since 1828, one in six states have cast their Electoral College votes for a candidate who failed to win the support of 50 percent of voters in their state

in 905 elections for governor in 60 years, the winning candidate received more than 50% of the vote in over 91% of the elections. The winning candidate received more than 45% of the vote in 98% of the elections. The winning candidate received more than 40% of the vote in 99% of the elections

Since 1824 there have been 16 presidential elections in which a candidate was elected or reelected without gaining a majority of the popular vote.--  including Lincoln (1860), Wilson (1912 and 1916), Truman (1948), Kennedy (1960), Nixon (1968), and Clinton (1992 and 1996).
