I'll be watching and blogging the YouTube debate tonight. More evidence of Giuliani sleaze is emerging:

The expenses first surfaced as Giuliani's two terms as mayor of New York drew to a close in 2001, when a city auditor stumbled across something unusual: $34,000 worth of travel expenses buried in the accounts of the New York City Loft Board.

When the city's fiscal monitor asked for an explanation, Giuliani's aides refused, citing "security," said Jeff Simmons, a spokesman for the city comptroller.

But American Express bills and travel documents obtained by Politico suggest another reason City Hall may have considered the documents sensitive: They detail three summers of visits to Southampton, the Long Island town where Nathan had an apartment.

I think we've only just begun to see the depth of Giuliani's ethical problems. And don't forget his undying support for and employment of a priest suspended because of serious and credible allegations of child molestation.
