Current estimates, Electoral:
If Bush wins, assuming Oregon and Florida go for him (Oregon is leaning that way): 278 out of 538, for 51.67%.
If Bush wins, assuming only Florida goes for him: 271 out of 538 : 50.37%
If Gore wins, assuming Oregon goes for Bush: 285 out of 538: 52.97%
If Gore wins, and takes Oregon as well: 292 out of 538: 54.27%
In 1876, Rutherford B. Hayes won election with 185 out of 369: 50.13%.
So the 1876 EC result was closer than the 2000, no matter how 2000 ends up.
Popular vote, current stats by this morning’s Washington Post:
Al Gore: 48,707,413
George Bush: 48,609,640
a difference of less than 100,000. (around .01%)
In 1880, James Garfield had 4,454,433; Winfield Hancock had 4,444,976: a margin of less than 10,000. (around .01%)
In 1884, Grover Cleveland had 4,875,971; James Blaine had 4,852,234: a margin of less than 25,000. (around .4%)
In 1888, Benjamin Harrison had 5,445,269; Grover Cleveland had 5,540,365; Harrison won the EC even though he lost the popular vote by almost 100,000. (around 1.1%)
So the difference in votes, percentage-wise, is about what it was in 1880. The difference, number-wise, is higher than in 1880 and 1884. And should Bush win, he’ll be losing less in the popular vote than Benjamin Harrison did in 1888.
