This isn't surprising:

Asked how they feel about the fact that their choice is the party’s nominee, 50 percent of Obama’s current voters say they are “enthusiastic.” Just 16 percent of McCain’s supporters say that about his candidacy.

But the 2004 contrast is interesting:

Even in polls taken just before the 2004 election...67 percent of Bush voters said they supported him strongly, compared with just 49 percent of Kerry voters. And while 37 percent of likely Republican voters said they would be “excited” by a Bush win, just 24 percent of likely Democratic voters said they would be “excited” by a Kerry victory.
