If Chris Christie did decide to run for president, he'd need to explain the Hudson Tunnel

NY Times: "N.J. to Repay U.S. $95 Million Over Hudson Tunnels":

On Friday [September 30], Gov. Chris Christie and Ray LaHood, the federal transportation secretary, announced that New Jersey would pay back $95 million that the federal government had provided for a pair of rail tunnels under the Hudson River that were projected to cost $8.7 billion. The effort, known as Access to the Region’s Core, or ARC, was one of the biggest public-works projects under way in the country when Mr. Christie decided to cancel it one year ago.

Mr. Christie maintained that his state could not afford to shoulder potentially huge cost overruns on the project, which would have doubled the train capacity between New Jersey and New York City. His unilateral decision to scrap the tunnels enraged Senator Frank R. Lautenberg, who had spent years lining up $6 billion in commitments from the federal government and the Port Authority of New York and New Jersey.

Mr. LaHood, who was also angry at Mr. Christie, demanded that New Jersey repay all of the $271 million in federal money that had gone toward the early stages of building the tunnels. The governor responded by declaring, “We are not paying the money back.”

And Republicans preach "fiscal responsibility" all the time. If Christie did join the primaries, campaign ads would devastate him over stealing about $150 million.

Most surprising of all? "Sarah Palin will not run for president in 2012" either. Otherwise the Republicans would've handed Obama an easy victory that year, something they do NOT want as Senate Republican leader Mitch McConnell famously said about the GOP agenda: "The single most important thing we want to achieve is for President Obama to be a one-term president."
