Simply put, it's because there us so very little difference between him and Hillary.
Will Christie defund obamacare?

If the economy and the country lasts until 2016, it will be on the very precipice of falling. If we don't try to get someone who will fight the progressive destruction of the country instead of going aong with it, it will fall. if Christie is on charge at the time, he and the GOP will get the blame for it.l
And wasn't there something before, about him wanting stricter gun control laws and he is now walking that back???
He has vetoed some gun control legislation just this past summer. However a little over a month ago, he had also approved some gun control legislation. Not sure what his advisers are telling him, however if he wants to run in 2016, he needs to convince social conservatives that he does not support gun control. The way to do this is to ease gun restrictions in NJ.
Christie also has serious issues with the economy in NJ. Many GOP'ers feel uneasy with his high tax policies. Before anyone can trust him to manage the U.S. economy, he needs to demonstrate that he could handle the current economic issues in NJ.
