Chris Christie gets good press, partly due to the fact that he's in the heart of MSM country in New Jersey and partly due to the fact that he's a moderate Republican; the media lap up telegenic pro-choice Republicans like a dog in 100-degree weather. He sounds conservative with his bombastic style but his politics are more right-of-center than Tea Party. He's up for reelection next year and is doing rather well post-Sandy, getting a 77% approval rating.
However, that isn't likely to translate into a run for the Presidency... at least not on the Republican side of the aisle. Being pro-abortion rights and centrist on climate change issues (which doesn't take much; merely respecting climate research will get a large part of the right hot and bothered) makes him a tough-sell with both economic and social conservatives. You'd have to have something going for you to see the remaining 60% of the GOP primary electorate who wouldn't reflexively veto such a passage, and Christie isn't that good; if Colin Powell and Rudy couldn't pull it off, Christie isn't likely to pull it off.
He's be a great independent candidate for president, triangulating between a stock-liberal candidate and a stock conservative candidate rather nicely; he'd be good for a third of the normal Republican vote and a third of the normal Democratic vote and kick butt with independents.
