Ten states – including California and Washington – and the District of Columbia have already signed on to the National Popular Vote Compact. It would guarantee that Electoral College votes from those states go only to presidential candidates who win the national popular vote.
The compact does not take effect until states with a collective 270 electoral votes adopt it. The current number stands at 165. Oregon has seven Electoral College votes.
Five presidents have lost the popular vote but won the Electoral College: John Quincy Adams in 1824, Rutherford B. Hayes in 1876, Benjamin Harrison in 1888, George W. Bush in 2000 and Donald Trump in 2016.
