Chris Christie on the role of the VP candidate: “No one’s saying, ‘I’m not sure about this Obama guy but, boy, I love Biden,’” Christie said, according to video of the news conference. “No matter who Governor Romney picks, if the people of the United States are not convinced that he is the right man to be president of the United States right now, no matter who he picks for vice president, they’re not voting for him and by the same token that went for President Obama four years ago.” (ABC)

AEI’s Jonah Goldberg wants to see more gaffes from Mitt Romney: “One of the few things Americans on both sides of the partisan divide can agree on is that this election is shaping up to be vexingly petty. The hunt for gaffes — some real, many imagined — has taken over. Romney’s recent overseas tour, we are told, produced three: An impolitic, if defensible, statement about Britain’s preparations for the Olympics; a statement about the importance of culture in economic development; and when an aide to Romney dressed down a reporter with an inflated sense of entitlement.” (USA Today)

“A year ahead of the mayoral race, pro-“labor” advocates are trying to strongarm City Council Speaker Christine Quinn into holding a vote on a bill requiring employers to offer sick leave. Quinn should keep resisting, as she did when the topic last came up two years ago: The bill could cost the city thousands of entry-level jobs,” writes Manhattan Institute’s Nicole Gelinas.
