Update: A couple thoughts from swimming freestyle:
1. If Obama gets above 50.1 percent, it will be the highest percentage for a Democratic nominee since Lyndon Johnson in 1964.
2. If Obama surpasses 53.4 percent nationally, he will post the highest popular vote share for any nonincumbent candidate of either party since 1952 -- and if he can somehow push that figure over 55.2 percent, he will be able to boast the highest share for a nonincumbent president since 1932.
3. Unless he finishes second, or somehow the national turnout dips under 125 million (both campaigns expect at least 130 million, with Obama's team projecting a number still higher than that), Obama will receive more votes for president than any candidate in presidential history.
4. Among winning candidates, and presuming record turnout rates by African-Americans and projected performance rates among and expected growth of the Hispanic vote, Obama should win a higher share of nonwhite votes than any major-party candidate (winner or loser) in history.
