By all records I can find, George Washington won every single popular vote in states that had a popular vote in 1788. Maps commonly show the popular vote count for only Pennsylvania and Maryland, even though Delaware, Massachusetts, New Hampshire, and Virginia seem to also have voted through popular vote. 1792 also seems to be a similar story.

How did George Washington win 100% of the popular vote? How different were the ballots from state to state? Did Maryland and Pennsylvania actually only have George Washington on the ballot or were people actually voting for electors? If people actually chose electors rather than a candidate, when did the actual Presidential candidates begin to appear on ballots in America? Do any of the ballots still exist today?
