From Michael Moore's “17 Reasons Not to Slit Your Wrists”:

Dear Friends,
Ok, it sucks. Really sucks. But before you go and cash it all in, let's, in the words of Monty Python, “always look on the bright side of life!” There IS some good news from Tuesday's election.
Here are 17 reasons not to slit your wrists:
1. It is against the law for George W. Bush to run for president again.

2. Bush's victory was the NARROWEST win for a sitting president since Woodrow Wilson in 1916.

3. The only age group in which the majority voted for Kerry was young adults (Kerry: 54%, Bush: 44%), proving once again that your parents are always wrong and you should never listen to them.

4. In spite of Bush's win, the majority of Americans still think the country is headed in the wrong direction (56%), think the war wasn't worth fighting (51%), and don’t approve of the job George W. Bush is doing (52%). (Note to foreigners: Don't try to figure this one out. It's an American thing, like Pop Tarts.)

        
This open letter by Michael Moore is in response to George Bush’s re-election.  Moore, a fervent yet realistic anti-Bush filmmaker, is somewhat disenchanted that all of his efforts have been for naught.  Recognizing that his supporters share his feelings, he continues his crusade against Bush with his sarcastically titled piece “17 Reasons Not to Slit Your Wrists.”  He mocks Bush’s re-election, making it seem like little more than a pyrrhic victory.  Bush had “the narrowest win” in almost a decade, and over half of the country disapproves of the job he is doing.  He is disappointed that Bush will get to serve the maximum eight years.  He tries to retain some optimism with a quote from the Monty Python comedy troupe but admits that the loss “really sucks.”
