Look for Bush to concede.
The current administration will seek the goodwill available from concession, and then claim they were robbed during the election.
But they will look to have it both ways; bigger men, looking out for the nation, by conceding(even though they will have lost decisively), and victims of fraudulent elction process.
Go read Al Gore's concession speech, and watch the party machine of the Republican's claim that they were defrauded of victory.
When the Democratic party's representative conceded in 2000, the Democratic party did not claim that they were defrauded in the lection, individuals, did. The party did not.
When Bush loses, he will graciouslt concede, and the party will go to war on the legitimacy of the Kerry presidency.
Very different. But it won't be noted as a difference in the press.
