TORONTO - New attack ads launched by Ontario's governing Liberals "smack of desperation" and show the party doesn't believe it can win the fall election on its record alone, opposition parties said Tuesday.

"You've got the stench of fear here, especially for the Liberals to be doing this sort of low life negative advertising in the pre-writ period, when they're not covered by election spending rules," said New Democrat Peter Kormos.

"I don't think Ontarians buy it, I don't think they like it."

The 30-second ad released Tuesday features Progressive Conservative Leader Tim Hudak and newspaper comments saying that he treats voters like "dolts" and "chumps" and lacks a credible platform.

"Reviews for Hudak's platform are in, here's what people are saying," the narrator says.

"Hudak refuses to tell voters the truth," reads one quote from the Globe and Mail.

"Harris history about to repeat itself," adds another from the Hamilton Spectator.
