"They are both horribly flawed candidates," the former New York governor said a day before the primary in his state.
Trump and Clinton are way ahead of their rivals in polls in New York, where they both live. They also have high negatives among voters.
Trump got a 24 percent positive rating and a 65 percent negative for a net-negative 41 percent, a historic low for a major presidential candidate in the NBC/Wall Street Journal poll. Clinton's net-negative rate was 24 percent, reflecting a 32 percent positive rating and a 56 percent negative score.
The solution in both cases, said Pataki, "nominate somebody else."
