U.S. Constitution, Article II, Section 1, Clause 2
Maine and Nebraska are the only states that do not award all of their electoral votes under multiple-winner plurality. In both states, the state at large has two electoral votes elected unti multiple-winner plurality. Each congressional district in these states also has a single electoral vote allocated using single-winner plurality, making it possible for the state to give electoral votes to multiple candidates.
Indiana cast its 11 electoral votes for Donald Trump in the 2016 election.
Most states always give 100% of their electoral votes to the candidate with a simple majority of popular votes. Therefore, with three candidates, it is theoretically possible to be elected unanimously with only 34% of the popular votes.
I think it was Mitt Romney
In the 1984 election Ronal Regan received 525 (97.58%) of the 538 electoral votes. Walter Mondale received 10 electoral votes from his home state of Minnesota and 3 electoral votes from the District of Columbia.
In 2008, Barack Obama received 0 electoral votes from Georgia, losing Georgia's 15 electoral votes to John McCain whom received 2,048,744 votes to Obama's 1,844,137 votes.In 2012, the election has not yet taken place. Projections indicate Georgia is leaning to give 16 electoral votes to Mitt Romney.
Donald Trump received 4,617,886 votes to Hillary Clinton's 4,504,975 votes, winning Florida's 29 electoral votes.
Congress decides. Article 2, Section 3 of the Constitution provides that Congress may determine the time and choosing the electors and the day on which they shall give their votes; which day shall be the same throughout the United States.
You need at least 270 electoral votes to win. The fewest number of states you could win is 11. They would have to be: Ca-55, Tx-34, Fl-27, Ga-15, Nc-15, NJ-15, Pa-21, Ny-31, Oh-20, Mi-17, Il-17 No other combination of 11 states could give you 270 electoral votes. Conversely you could win 39 states and DC and still lose. It should be noted that the residents of USA. territories cannot vote for The President. If they were given electoral votes the same way that states were this answer could change to 10 because you could make up the remainder with territorial votes. If however each territory was given three votes (as would be expected as that is the minimum number given to a state) then a candidate would need 277 votes and the answer would actually change to 12. If the electoral college were eliminated in favor of a popular vote system (which it should be) than you would not have to win any states as long as you won at least one territory.
In the 2016 Presidential campaign, Hillary Clinton received 729,547 votes to Donald Trump's 1,318,255 votes, losing Alabama's 9 electoral votes.
The Congress may determine the time of choosing the electors and the day on which they shall give their votes; which day shall be the same throughout the United States.
One could win the US presidential election without the ten states with the highest number of electoral votes (256), although since numbers nine through eleven each have 15 votes if all eleven of the states with the most electoral votes went for one candidate there is no way the other candidate could win (271 votes against). In the 'top ten ' scenario, all of the remaining states, with the exception of Massachusetts (12 votes) would have to be won by the candidate collecting electoral votes from the smaller (when calculated by electoral votes) states.
