Once again defying conventional wisdom, Jerry Brown announced at a campaign rally today that he is a vampire.

"I won't raise taxes, but I do want your blood," Brown told supporters.

The effect of Brown's revelation on the governor's race was unclear. "Generally speaking, it isn't a good idea to admit being a monster," one political analyst said.

In Delaware, for example, U.S. Senate candidate Christine O'Donnell had to run ads denying she was a witch.

But, in California, being undead could be viewed as an asset. "A vampire governor is our best defense against werewolves," said Timothy Morton, a 25-year-old grad student.

Another voter, Polly Adams, 42, said she had been reluctant to vote for Brown because of the possibility he would die in office and Gavin Newsom would take over. "But if Brown is a reanimated corpse, that's no longer an issue," she said.
