More pig crate fallout for Gov.

Several high-profile animal rights activists are leveling some blistering criticism at Gov. Chris Christie.

The latest to lash out at him is Cher.

In an explosive tweet, she called Christie a "despicable bully," who should forget POTUS.

The tirade referred to Christie's veto of a bill that would ban confining gestation crates for pregnant pigs.

New Jersey Democrats have manufactured the issue, which has zero impact here, but far-reaching implications in the key presidential primary state of Iowa.

The veto has set off a fiery debate on both the issue and Christie's future political ambitions.
