A little more. In 5 elections, the popular vote majority has lost. In 1824, John Quincy Adams won over Andrew Jackson, they were of the same party. Adams was the son of a past president(note this). In 1876, Hayes, a republican, won over Tilden, a democrat. In 1888, Harrison, a republican, won over Cleveland, a democrat and sitting president. In 2000, Bush, a republican and son of a past president, won over Gore, a democrat. In 2016, Trump, a republican, won over Clinton, a democrat.
Every time except one, a republican was awarded the presidency over a democrat with a popular vote majority. There is a form of gerrymandering in the electoral college. It has been proven 4 out of 5 times.
