June 13 (UPI) -- Five times in U.S. history, the presidential candidate who won the national popular vote did not win the White House -- including two of the last five elections. Those losses have spurred a national movement to change the way elections are won.
Since Democrat Hillary Clinton lost the 2016 race, with nearly 3 million more votes than Donald Trump, a number of states have passed laws to award their electoral votes to the winner of the national popular vote. Fifteen states and Washington, D.C., have so far enacted such laws -- with the latest, Oregon, joining Wednesday.
It's a movement that's been growing since 2006, when the National Popular Vote Interstate Compact -- a non-profit with the goal of enacting a system to elect the popular vote winner -- formed to persuade states to join.
"The purpose of this legislation is to guarantee the presidency to the candidate who gets the most votes in all 50 states and the District of Columbia," National Popular Vote Director John Koza said.
The compact began five years after George W. Bush took office after winning the 2000 election, despite losing the popular vote to Al Gore by about 500,000 ballots. The same thing happened to deny Grover Cleveland in 1888, Samuel J. Tilden in 1876 and Andrew Jackson in 1824.
How it would work?
Presently, a state's electoral votes go to the candidate who wins the state popular vote. But there is no law that requires states to award their votes this way. Each state can decide how to award their votes, which is why some are now split by districts.
If enough states join the movement -- those that carry 270 votes or more -- the compact would take effect. Until it reaches the 270-vote mark, however, all states will continue to award votes the traditional way.
"The winner-take-all method of awarding electoral votes is not in the Constitution, it was never debated by the constitutional convention, it wasn't in the Federalist Papers, the founders never endorsed it and it didn't become prevalent in many cases until the Founding Fathers' children were dead," said Koza.
"The fact is it's just state law and it's changeable by state law," Koza said.
Proponents argue that the National Popular Vote would give every American voter an equal say in the election. Right now, the argument goes, many Democrats in heavily GOP states and Republicans in solidly progressive states see theirs as wasted, or meaningless, votes.
Also, Koza added, the current system encourages candidates to focus their campaigns on just a handful of key states, called "swing" or "battleground" states. It's why Republican candidates almost never stump in Hawaii and Democrats nearly always bypass Utah, for example.
"I'm excited about [the National Popular Vote coalition] because I think it will encourage candidates to spend more time in states like ours," Oregon Gov. Kate Brown said when she signed the new law Wednesday. "I think it's really important for Oregon to part of the national conversation regarding the presidential election."
In the 2016 election, 94 percent of campaign events took place in 12 states where Trump's support was between 43 and 51 percent, while two-thirds of all events were in Ohio, Florida, Virginia, North Carolina, Pennsylvania and Michigan, according to the coalition.
If and when it reaches the 270-vote mark, the interstate compact would take effect on July 20, meaning it could influence the 2020 presidential election if the remaining needed states join in time.
Where do the states stand?
The 15 joined states and Washington, D.C., bring a combined total of 196 electoral votes -- meaning the movement needs to sign up states with just 74 more to give the compact legal force.
States that have joined are California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Massachusetts, Maryland, New Jersey, New Mexico, New York, Rhode Island, Vermont and Washington. Washington, D.C., has also joined.
Will the remaining 74 electoral votes come? Right now, legislation to join has passed at least one legislative chamber in eight states -- Arkansas, Arizona, Maine, Michigan, Minnesota, North Carolina, Oklahoma and Nevada. Those states, if they enacted their bills, would put the compact over the top, with 271 electoral votes.
The Maine Senate last month passed legislation to join, but it was defeated in the House. The same happened in Nevada, where the legislature passed the bill, but it was vetoed by Gov. Steve Sisolak. The governor argued the movement could give smaller states like Nevada less influence in elections.
"[It] could diminish the role of smaller states like Nevada in national elections and force Nevada's electors to side with whoever wins the national popular vote, rather than the candidate Nevadans choose," Sisolak said in a statement after his veto.
Legislation to join the movement has been introduced in all 50 states, but 10 -- including Florida, South Carolina, Virginia, Texas, Indiana, Iowa, Wyoming and Idaho -- have declined to give it a hearing. Florida is considered a key battleground state in each presidential election.
If the movement succeeds, it would seem to align -- and clash -- with the will of most Americans. A Gallup poll last month found 55 percent of respondents favored eliminating the Electoral College, while 43 percent opposed. However, most (53 percent) rejected the idea of states circumventing the college in the fashion the national compact is attempting.
