Republican Rudy Giuliani said Thursday he'd made a mistake in recommending his New York City police commissioner for a Cabinet job but asserted his good decisions far outweigh his bad.

As mayor, he said, he made hundreds of thousands of decisions. If voters in the presidential race consider that record, he said they can then "say to themselves that if he makes the same balance of right decisions and incorrect decisions as president, the country will be in pretty good shape."

Giuliani was asked at a news conference outside the Dubuque County Courthouse whether he still stands by Bernard Kerik, the former police commissioner who could be indicted this week. He sidestepped that question and said the issue has to be decided in the courts.

"A lot of public comment about it is inconsistent with it's getting resolved in the right way in the courts," he said as campaign aides prepared to usher him to his next stop.

In 2004, Giuliani endorsed his protege's nomination to head the Department of Homeland Security. Only days after President Bush introduced the nominee, Kerik announced he was withdrawing because of tax issues involving his former nanny.

A grand jury has been hearing evidence in Kerik's case on tax evasion and other charges for several months, and was expected to vote Thursday on whether to indict him.

Giuliani argues that the controversy shouldn't overshadow his own crime-fighting record.
