What's with the GOP's "utter lack of triumphalism"?

"In 1994, riding their previous tsunami, Republicans literally danced in the Washington streets and partied for 48 hours. In 2008, Democrats wept and sang. There was none of this last night, even though the GOP victory might have been larger and more decisive than either of those."

Why so somber?
	They know they aren't really popular. Just the alternative to something despised.
	Jubilation has a way of biting you in the ass 2 years later.
	Things are so bad that it would be in bad taste to look all happy.
	They won't really be able to do anything and want to keep expectations low.
	The Rally to Restore Sanity restored sanity.
	These people are genuine adults, acting like adults.
