New Jersey Gov. Chris Christie ripped California Gov. Jerry Brown on Monday, saying that the state’s voters should have elected Meg Whitman but instead went with a “retread” who is failing to lead.

“California made the bad choice by going with an old retread,” Christie told California’s delegation to the Republican National Convention, a crowd that lapped up his message. “Let me tell you this – I cannot believe you people elected Jerry Brown over Meg Whitman. … Jerry Brown. Jerry Brown? I mean, he won the New Jersey presidential primary over Jimmy Carter when I was 14 years old.”

Christie said the 74-year-old, three-term governor told him that he’s not trying to raise taxes, that he is allowing voters to decide by putting a tax proposal on the ballot.

“Man, that’s leadership, isn’t it?” Christie said.
