Bloomberg's allegation

NY Post:

February 20, 2008 -- Mayor Bloomberg charged yesterday that "fraud" was behind the unofficial results in the New York Democratic presidential primary that produced zero votes for Barack Obama in some districts.

"If you want to call it significant undercounting, I guess that's a euphemism for fraud," said the mayor.

Unofficial tallies on election night gave Obama no votes in 78 out of more than 6,000 election districts.
