Nixon may have been a lot of things, but he was honorable. He conceded to Kennedy in 1960 and he resigned from office during Watergate. He loved this country more than he loved himself.
The days of honorable behavior in politics is over for both political parties, though for different reasons. It's over for Dems because they no longer know its definition. Their party has been hijacked by the radical peace-niks from the 1960s whose entire outlook on life is socialistic in nature. It's perfectly acceptable to divide the nation during a war, or if that doesn't work, conduct massive voter fraud. After all, the ends justify the means, right? Democrats who are of the WWII generation -- people who recognize honor and sacrifice for country -- no longer represent nor recognize the Democratic party.
But for Republicans, the end of honorable behavior is being forced upon them. They are no longer afforded the luxury of displaying honorable behavior, particularly to their defeated opponents, without being taken advantage of. If Bush waits longer than today to publicly declare victory and tell the country to unite and move on, the Dems will interpret that as weakness and be more determined than ever to drag this out for weeks or even months.
